I'm trying to make a working install of Ubuntu 14.04 on a Toshiba Satellite U200. Ubuntu is running pretty well, except there is absolutely no audio.

I have already followed all the advice in the Sound troubleshooting page, and the results were:

  • I checked the audio settings tons of times: it is not muted, and the volume is at 100%. I can see the indicator on the panel and it seems active and not muted.

  • The sink is listed if I use pacmd and the list-sinks command. However the output is the following:

    $ pacmd
Welcome to PulseAudio! Use "help" for usage information.
>>> list-sinks
1 sink(s) available.

            properties:

    I don't really like the state: SUSPENDED, nor the used by: 0, linked by: 0 and, at the end, available: unknown, however I'm not really sure what all this output means.

  • When playing the test sounds I don't hear anything, even when using sudo. The user wasn't in the audio group, I have added the user to the group and nothing changed.

  • I tried to log in the guest session, but the audio doesn't work either.
  • The sound card is recognize by Ubuntu and aplay -l does show it.
  • find /lib/modules/uname -r| grep snd does find tons of modules, so the drivers seem to be there.

  • Output of lspci:

    $ lspci -v | grep -A7 -i "audio"

  • I don't understand whether the sound card is supported. I can see ICH7 in the Intel list, but I cannot find NM10/ICH7. Also it seems like ICH7 devices use the snd-intel8x0 driver, which I have:

    $ find /lib/modules/`uname -r` | grep snd-intel8x0
/lib/modules/3.13.0-24-generic/kernel/sound/pci/snd-intel8x0.ko
/lib/modules/3.13.0-24-generic/kernel/sound/pci/snd-intel8x0m.ko

Does somebody know how to fix this issue?

On this page it is me tioned that on some toshiba laptops not muting headphones may sometimes automatically mute the master volume. I have tried a lot of combinations of mute/unmute the various channels but nothing worked.

Later on the same page suggest doing:

$ sudo iecset audio on

And I get the following response:

control "IEC958 Playback Default" (index -1) not found

I don't whether this might be useful, but the internal microphone works perfectly. I can record sound but I'm unable to play it.

I just noticed that when doing alsa force-reload, it says that it fails to unload some modules:

$ sudo alsa force-reload

I was having your same issue. I found this:

https://bbs.archlinux.org/viewtopic.php?id=175110

So I used the following steps:

  1. add "blacklist i82975x_edac" to /etc/modprobe.d/alsa-base-blacklist.conf

  2. sudo modprobe -r i82975x_edac

  3. sudo alsa force-reload

I did see this:

(failed: modules still loaded: snd-hda-codec-analog snd-hda-codec snd-hwdep snd-pcm snd-page-alloc snd-timer)

But sound now does work.

Those of you who are having trouble with this type of sound card:

Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller

You shouldn't uninstall anything. It is enough to change the default output device in your alsa settings. It is normally set to the speakers, so change that to analog headphones and your problem should be solved. I've had this issue on several different machines and this solution has always worked.
