| flip | hey, my audio was showing as dummy driver and i uninstalled alsa and reinstalled then restarted alsa and nothing. THis is the second time it has happened. any idea what to do? please? | 01:45 |
|---|---|---|
| wxl | flip: it happens sometimes bnut not other times/ | 01:48 |
| flip | how do you fix it? | 01:49 |
| wxl | i await your answer to my question to help figure that out | 01:49 |
| flip | if that was question then not usually. I reinstalled the OS to get the sound to work and it did but now its not working again | 01:50 |
| wxl | so it works sometimes, but not other timese | 01:50 |
| flip | i thought that was an answer at first | 01:50 |
| wxl | and there's no pattern to when it works and doesn't | 01:50 |
| wxl | right? | 01:50 |
| flip | pretty much but it hasnt worked consistently since it didnt work | 01:50 |
| wxl | well consistently is the key | 01:50 |
| wxl | random problems usually ahve random causes | 01:51 |
| flip | i followed some fourm advice and uninstalled alsa and pulse audio then reinstalled them and forced a restart of alsa | 01:51 |
| wxl | my guess is that either your sound card is failing or it's not properly connected to the motherboard | 01:51 |
| wxl | if `lspci` doesn't see the card, it doesn't matter what software you have, it won't work | 01:51 |
| flip | now the audio icon is gone from the top right...or the bar where wifi, battery...that stuff is | 01:52 |
| wxl | you need to look lower level | 01:52 |
| wxl | first confirm the kernel sees the hardware with `lspci` | 01:52 |
| flip | 00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 02) | 01:53 |
| wxl | so it does see it which is good | 01:53 |
| wxl | try `lspci -nnk | grep " Audio " | grep driver` | 01:53 |
| flip | include the `? | 01:54 |
| wxl | no, that indicates the start and end of the command | 01:54 |
| flip | nothing ahppens, it just goes to the next line | 01:55 |
| wxl | oh well that's remarkable | 01:55 |
| wxl | oh derp | 01:55 |
| wxl | i did this wrong | 01:55 |
| wxl | try `lspci -nnk | grep -A2 " Audio " | grep driver` | 01:55 |
| flip | lspci -nnk | grep " Audio " | grep driver | 01:56 |
| flip | Kernel driver in use: snd_hda_intel | 01:56 |
| wxl | ok, so you have a driver | 01:56 |
| wxl | so that's all good | 01:56 |
| flip | so far so good | 01:57 |
| wxl | you have a wav file handy? | 01:57 |
| flip | maybe, i just reinstalled ubuntu 14.04 | 01:58 |
| flip | then added apps and whatnot...but ill see would youtube wrok or specifically a wav? | 01:58 |
| wxl | preferably a wav | 01:58 |
| wxl | you can grab this http://www.nch.com.au/acm/11k16bitpcm.wav | 02:00 |
| flip | hu | 02:00 |
| flip | its working | 02:00 |
| flip | it asked me to click something to activate vlc | 02:00 |
| flip | i did that and it worked... | 02:01 |
| wxl | so i was going to have you test alsa, but it seems you've moved a bit upstream :) | 02:01 |
| wxl | which is fine | 02:01 |
| wxl | so what is NOT working? | 02:01 |
| flip | well now the video for class is working with sound so i assume everything works | 02:01 |
| wxl | okie dokie | 02:02 |
| flip | the identifier icon is not on the right though | 02:02 |
| wxl | also keep in mind if you're having problems with video that might be a totally different issue unrelated to sound itself | 02:02 |
| wxl | i always start at the lowest level: | 02:02 |
| flip | it was only the sound from the video, the video was working otherwise | 02:02 |
| wxl | 1. make sure the hardware is detectged | 02:02 |
| wxl | 2. make sure the kernel driver is in use | 02:02 |
| wxl | 3. make sure alsa is behaving (i use `aplay`) | 02:03 |
| wxl | 4. make sure pulse is working (i don't use it so figure that one out yourself) | 02:03 |
| wxl | 5. make sure something basic like an mp3 and/or a video plays with vlc | 02:03 |
| wxl | 6. then move to the browser | 02:04 |
| wxl | the browser could be a whole array of problems | 02:04 |
| wxl | usually the simplest solution is to use a different browser | 02:04 |
| wxl | of course it could be a browser plug int | 02:04 |
| wxl | etc | 02:04 |
| wxl | good luck :) | 02:04 |
| flip | thanks | 02:04 |
| flip | i think my audio was attributed to something incorrectly...im not sure but i figure it asked me to use VLC so can i set it to only use VLC? | 02:06 |
