My audio device not working

Question

I have been setting up a new CrunchBang Linux and my sound doesn't work. When I type lspci -v command and alplay -l command in command prompt I can see that my sound card is connected and detected.

Results:

ziga@ziga-laptop:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: HDA Generic [HDA Generic]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

More results:

ziga@ziga-laptop:~$ lspci -v
00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) (rev 40)
    Subsystem: Hewlett-Packard Company Device 1604
    Flags: bus master, slow devsel, latency 64, IRQ 16
    Memory at 90400000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: HDA Intel

Well I've figured out that my audio card model is ATI SBx00 and I can't find it on www.alsa-project.org although my soundcard already worked with alsamixer when I was using Xubuntu 12.04. And it also worked with previous versions of CrunchBang Linux. So I've tried to reconfigure alsamixer by using command alsamixer, pressing F5 and then increasing all sliders to the max like shown below.

When in alsamixer i tried to hit F2 and this menu pops out:

┌───── Select File ──────┐

Below i will paste outputs of all of all menu options, here it goes:

When i press F6 i get the menu for selecting sound card which looks like this:

┌───── Sound Card ──────┐

Answer 1

Try F5 in alsamixer.

you will see All possible options. maybe there is something muted by default.

what do you see pressing F2 and F6?

Answer 2

Kernel 2.6.32 is from 2009; you cannot expect that old drivers to work with newer hardware.

Try to get a newer CrunchBang kernel, or switch to another distribution.

Answer 3

Kindly look into these two links which people have frequently used to solve their audio related problems after installing Ubuntu 12.04 PP (including me) . Here they are :

Look at the second link for this one has helped me a lot for fixing similar kind of issue in my HP laptop.

Hope this helps you .

Answer 4

It sounds like you are missing a sound module. Here are some ideas you can try:

• Since the soundcard is correctly detected (your headphones work), it sounds like you are either missing the module that controls the pc speakers, or you have the speakers muted. Have you tried switching devices by hitting F6 in alsamixer? If you switch from default to 0 HDA ATI SB, you may get more options. On my system, I get many more channels, including "Front". Make sure that "Front" is set to maximum volume.

• The alsa-info.shscript should give you some more useful information. Try running it and linking to its output please:

  $ wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh
  

  That way we can check what modules you have loaded and if anything is missing.

• alsaconf is a script to configure alsa. Although it is no longer included in the alsa-utils package, it may still be worth looking into. I found an old version here.
