| 18:48 | < Tarinaky> | Don't suppose a Linux user can help me figure out why my sound's not working since I moved my box? |
| 18:49 | < Namegduf> | You disrupted the Feng Shui. |
| 18:49 | < Namegduf> | Move it back. |
| 18:50 | < Namegduf> | Seriously... not working, okay. |
| 18:50 | < Namegduf> | You boot, start an app that should play sound, it doesn't play sound? |
| 18:51 | < Tarinaky> | mpd doesn't produce sound |
| 18:51 | < Namegduf> | Obvious thing, have you checked the volume settings? |
| 18:51 | < Tarinaky> | To give the problem a specific title. |
| 18:51 | < Tarinaky> | I checked alsamixer and my headset's hardware volume. |
| 18:51 | < Tarinaky> | Both check out. |
| 18:52 | < Namegduf> | Hmm. |
| 18:52 | < Tarinaky> | mplayer has the same problem (tested it on an avi) |
| 18:53 | < Namegduf> | What does "lsof /dev/snd/*" say? |
| 18:53 | < Namegduf> | This will reveal if your sound hardware is being bogarted by something, or if the sound drivers are not even loaded. |
| 18:53 | < Tarinaky> | bash: lsof: command not found |
| 18:54 | < Namegduf> | Yay. |
| 18:54 | < Namegduf> | Could you install that? It's quite useful, displays all processes with an open handle on something. |
| 18:55 | < Tarinaky> | Installed it, ran it. |
| 18:55 | < Tarinaky> | Zero rows returned. |
| 18:55 | < Namegduf> | Okay, so the files exist, and are not being controlled by something. |
| 18:55 | < Namegduf> | Hmm. |
| 18:55 | < Namegduf> | Would you know if you had PulseAudio or something similar installed? |
| 18:56 | < Tarinaky> | Unless I have an evil clone who knows my password and has been installing things behind my back. PulseAudio isn't installed. |
| 18:57 | < Namegduf> | Yeah, that's a lot less likely than the Feng Shui idea. |
| 18:57 | < Namegduf> | Do you have any other speakers than your headset? |
| 18:57 | < Tarinaky> | No. |
| 18:57 | < Namegduf> | Have you tried the headset in another system to check it is okay? |
| 18:57 | < PinkFreud> | Tarinaky: check alsamixer again and make sure the relevant channels are not muted. |
| 18:57 | < Tarinaky> | My headset can be made to produces sound independently of a computer. |
| 18:58 | < Namegduf> | Okay. |
| 18:58 | < Tarinaky> | But I don't have another system to try it with. |
| 18:58 | < Namegduf> | Does your computer have ports on the front AND back for headphones? |
| 18:58 | < Tarinaky> | Yes. |
| 18:58 | < Tarinaky> | I tried both. |
| 18:58 | < Namegduf> | Have you trie-okay. |
| 18:59 | < Namegduf> | If PinkFreud's idea doesn't work, the last thing I can think of is trying dmesg and seeing if anything likely shows up. |
| 18:59 | < Tarinaky> | PinkFreud: The only muted playback channels are Front Mic, Line in, CD, Mic, S/PDIF (Don't know what this is) and Beep. |
| 18:59 | < Namegduf> | Er, increase CD |
| 18:59 | < Namegduf> | See if that does something |
| 19:00 | < Tarinaky> | It does not. |
| 19:00 | < Namegduf> | Okay. |
| 19:01 | < Namegduf> | Can you go to mplayer's settings, and check that the audio driver is set to alsa? |
| 19:01 | < PinkFreud> | most of those are recording (input) channels, save for CD, and maybe SPDIF |
| 19:01 | < Namegduf> | More precisely, Preferences->Audio, then there's a list. |
| 19:01 | < Tarinaky> | Namegduf: Umm... mplayer doesn't have a GUI. |
| 19:01 | < Namegduf> | mplayer minus a GUI |
| 19:02 | < Namegduf> | Okay, I don't know how to use that. |
| 19:02 | < Tarinaky> | mplayer with the GUI turned on doesn't work for me. |
| 19:02 | < Namegduf> | Okay. |
| 19:02 | < Tarinaky> | And I never invested enough time to care. |
| 19:02 | < Namegduf> | I'm really low on ideas. |
| 19:03 | < Namegduf> | It sounds like the hardware/connections is okay, the OS is detecting the hardware, and you've tried multiple programs, so it probably isn't those. It could be a screwed up ALSA config, but that shouldn't happen unless you or someone else created an ALSA config in the first place. |
| 19:03 | < Tarinaky> | mpd is configured to use alsa (all other output devices are commented out) |
| 19:03 | < Namegduf> | Okay. |
| 19:04 | < Namegduf> | Hmm. |
| 19:05 | < Namegduf> | Could you run stat on the files in /dev/snd and see if they're A) group writable B) you're in said group. |
| 19:05 | < Serah> | more magic? |
| 19:05 | < Namegduf> | Today, the lights are all wrong |
| 19:05 | < Tarinaky> | Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) |
| 19:06 | < Namegduf> | ANd pressing more buttons isn't fixing it. |
| 19:06 | < Tarinaky> | I'm guessing the group should be audio - yes? |
| 19:06 | < Namegduf> | Give me a moment to check. |
| 19:06 | | * Tarinaky 's user is in group audio. |
| 19:07 | | * Tarinaky tries sudo mplayer |
| 19:07 | < Namegduf> | One file is 0755, but the others are 0660 for me, with "audio" as the group. |
| 19:07 | < Tarinaky> | sudo mplayer ReservoirDogs.avi doesn't work either. |
| 19:08 | < Namegduf> | Hmm, there's another option. |
| 19:08 | < Namegduf> | What does "cat /proc/asound/cards" look like? |
| 19:08 | < Namegduf> | The thought I had involved another audio device. |
| 19:08 | < Tarinaky> | 0 [NVidia ]: HDA-Intel - HDA NVidia |
| 19:08 | < Tarinaky> | HDA NVidia at 0xdfdf8000 irq 22 |
| 19:08 | < Namegduf> | Is that the only thing in there? |
| 19:08 | < Tarinaky> | Yes. |
| 19:08 | < Namegduf> | Okay, looks likely to be right. |
| 19:09 | < Namegduf> | Hmm. |
| 19:09 | < Namegduf> | What OS? |
| 19:09 | < Namegduf> | Er, distro. |
| 19:09 | < Tarinaky> | Arch |
| 19:09 | < Namegduf> | Okay. |
| 19:09 | < Tarinaky> | I'm going to try Windows. BBS. |
| 19:09 | | Tarinaky [Tarinaky@Nightstar-f349ca6d.plus.com] has quit [Connection closed] |
| 19:09 | < Namegduf> | Maybe you're missing an alsa startup script. |
| 19:10 | < Serah> | As far as I understoof, he just physically moved the box, and that broke it. |
| 19:10 | < Namegduf> | Yeah, but that shouldn't do anything, so I had to revert to more manual steps. |
| 19:10 | < Namegduf> | Also, if it wasn't restarted since setup |
| 19:10 | < Namegduf> | The reboot could have done it. |
| 19:11 | < Serah> | There's gooks in the wires! |
| 19:11 | < Namegduf> | I have a new likely theory, at least. |
| 19:11 | < Namegduf> | Arch has manual boot configuration, because it's a shitty distro. |
| 19:11 | < Namegduf> | (Okay, no, it's fine, but that particular decision was stupid in my view) |
| 19:11 | < Serah> | GOOKS IN THE WIRE I TELL YOU |
| 19:12 | < Namegduf> | So they could be missing the ALSA service stuff every sane configuration sets up for you. |
| 19:12 | < Namegduf> | This is kind of like getting a copy of Windows with half its essential services set not to run. |
| 19:12 | < Namegduf> | I think it'd display behaviour like that. |
| 19:14 | | Tarinaky [Tarinaky@Nightstar-f349ca6d.plus.com] has joined #code |
| 19:15 | < Tarinaky> | Problem fixed. |
| 19:15 | < Namegduf> | What was it? |
| 19:15 | <@AnnoDomini> | Bugs crawled into the sound card. |
| 19:15 | < Tarinaky> | The transmitter dongle. |
| 19:15 | < Namegduf> | Transmitter dongle? |
| 19:15 | < Tarinaky> | When I put it in the 'on' position for some reason it hadn't actually turned on. |
| 19:15 | < Namegduf> | Ah. |
| 19:15 | < Tarinaky> | Wireless headset. |
| 19:16 | < Namegduf> | Yay, fixed. |
| 19:16 | < PinkFreud> | awesome |
| 19:16 | < Tarinaky> | It was only when I unplugged the charging cable it became apparent that it wasn't on. |
| 19:16 | < Tarinaky> | Since flashing lights are flashing lights. |
| 19:16 | < Serah> | Wireless headsets = Yucky. |
| 19:17 | < Tarinaky> | Beats breaking them by forgetting they're on and standing up. |
| 19:18 | < Serah> | Your wired headphones don't have a cord that supports standing up? |
| 19:18 | < Namegduf> | I destroy headphone wires. |
| 19:18 | < Serah> | Mine usually comoes with 3½ meters cord. |
| 19:18 | < Serah> | I do too. |
| 19:18 | < Namegduf> | I don't know why. |
| 19:18 | < Serah> | But I destroy wireless batteries even faster. |
| 19:19 | < Tarinaky> | Unrelated note - What's the key to boot in safemode on XP? |
| 19:19 | < Tarinaky> | Windows was playing silly buggers due to it currently being configured for a different (widescreen) monitor. |
| 19:19 | < PinkFreud> | http://googlesightseeing.com/maps?tw=1006&p=&c=&t=h&hl=en&ll=50.378683,-4.134657 &z=16&layer=c&cbll=50.378691,-4.134783&cbp=12,274.96,,2,0.86 - Party on Wayne. Party on, Garth. |
| 19:19 | < Namegduf> | I failed my Trivia - Windows check, sorry. |
| 19:19 | < PinkFreud> | Tarinaky: F8 |
| 19:20 | < Namegduf> | (It wasn't a hard roll, either...) |
| 19:20 | | * Tarinaky needs to be able to change the resolution without being able to see anything. |
| 19:20 | < Tarinaky> | Can safemode be used to this effect? |
| 19:20 | < Namegduf> | Safemode can/should be able to revert to 640x480, shouldn't it? |
| 19:20 | < PinkFreud> | Tarinaky: probably not, but it's worth a try |
| 19:20 | | * Namegduf doesn't really recall. |
| 19:21 | < Tarinaky> | Namegduf: How do I change the 'real' resolution from within safemode though? |
| 19:21 | < Namegduf> | Hmm. |
| 19:21 | < Namegduf> | It's either easy and I don't know the way, or registry hax time. |
| 19:21 | < Namegduf> | Which I also don't know. |
| 19:21 | < Namegduf> | Can't help, sorry. |
| 19:21 | < Tarinaky> | You know there's something wrong when Linux does something in a more usefriendly way >.> *cough* |
| 19:22 | < Tarinaky> | *userfriendly |
| 19:23 | < Tarinaky> | Ah. Apparently I need something called 'VGA mode' |
| 19:24 | < Tarinaky> | Which can be accessed by a process ill understood. |
| 19:24 | < Tarinaky> | Apparently it can be summoned using a pint of rat's blood and 2 pieces of wood but it's recommended that you use some candles and stuff to make it look flashier. |
| 19:25 | | * Tarinaky coughs - happy to have the snark out of his system. |
| 19:26 | < Serah> | GOOKS!?!? |
| 19:27 | < Serah> | Tar: Just uninstall your video driver in windows, it'll revert to 640x480. |
| 19:28 | < Serah> | Take it as an opportunity to update your video driver while you're at it. |
| 19:30 | < Serah> | Also, according to winows gooks stole my wireless net. |
| 19:30 | < Serah> | So typing this feels somewhat strange. |
| 19:30 | < Tarinaky> | Serah: There is no newer video driver. |
| 19:30 | < Tarinaky> | My card is getting on so to speak/. |
| 19:31 | < Namegduf> | That is a solution, though. |
| 19:31 | < Serah> | Then just disable it anyway. |
| 19:31 | < Tarinaky> | Anyway. The VGA mode looks to be the correct solution and I was only kidding about it being a difficult process. |
| 19:32 | < Tarinaky> | Apparently I have to hit F8 twice 'just after it boots' |
| 19:32 | < Tarinaky> | Which I presume means the loading screen. |
| 19:32 | < Serah> | Yes after bios init. |
| 19:32 | < Namegduf> | Just hammer F8. |
| 19:32 | < Serah> | As has been windows custom since ... ages. |
| 19:32 | < Namegduf> | :P |
| 19:32 | < Tarinaky> | Can't. Got to pass GRUB first. |
| 19:32 | < Serah> | Except in a less violent manner, because we like our keyboards. |
| 19:32 | < Namegduf> | Ah, yes. |

| 22:57 | <@McMartin> | You were dealing with, er, trie data structures not long ago. |
| 22:57 | <@McMartin> | I find myself in need of a refresher on them; do you have any handy links on this? |

| 22:58 | <@McMartin> | (Why yes, I was reminded of this by your typo) |
| 22:59 | <@Vornicus> | I don't really have a refresher handy other than the code I wrote for LZW. |
| 23:00 | <@Vornicus> | which is damn simple. |
| 23:02 | <@McMartin> | Hm |
| 23:03 | <@McMartin> | Wiki and digging through old textbooks it is, then |
| 23:03 | <@Vornicus> | Easiest way to implement it is a trie node is a (letter -> trie) |
| 23:03 | <@Vornicus> | map. |
| 23:03 | <@McMartin> | Right |
| 23:06 | <@Vornicus> | well, and whatever other data you need. then you just walk down the trie with each successive letter you see. |
| 23:06 | <@Vornicus> | cell phone "t9" uses a trie too, on numbers |
| 23:06 | <@Vornicus> | and then letter -> (trie, list of available spellings) |
