PostPosted: Mon Apr 09, 2012 2:49 am    Post subject: AMD A6, BeaverCreek HDMI Audio and Hudson Azalia [Solved] Reply with quote

I am trying to figure out how to use sound on this system. There are two vaguely relevant answers that I have found on the web, but neither seems to be good. One solution involves changing files in /usr/share (need I say more) and the other is only relevant to systems with audio hardware supported by different modules.

The problem is (I think) that that the audio output in use is the HDMI output, rather than the traditional audio jack. lspci shows 2 Audio cards:
lspci | grep Audio
00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI BeaverCreek HDMI Audio [Radeon HD 6500D and 6400G-6600G series]
00:14.2 Audio device: Advanced Micro Devices [AMD] Hudson Azalia Controller (rev 01)


However, looking further, both of these audio cards are supported by the same module (snd-hda-intel):

I think that I need to swap the order of the sound cards, but, since they use the same module, I am stumped on how I should do this. Perhaps a udev rule?

mgnut57,

That's right, the device order determines which device to use as the 'default' device, at least from ALSA's pov. I have an AMD A8 APU and my immediate need was to get analog audio from the green 3.5mm jack on my box. To that end this should help:

Code:

# grep Codec /proc/asound/card*/codec*
# /proc/asound/card1/codec#0:Codec: ATI R6xx HDMI
# /proc/asound/card2/codec#0:Codec: Realtek ALC892

# ls -la /proc/asound/
# dr-xr-xr-x 4 root root 0 Mar 25 15:03 card0
# dr-xr-xr-x 3 root root 0 Mar 25 15:03 card1
# dr-xr-xr-x 6 root root 0 Mar 25 15:03 card2
# -r--r--r-- 1 root root 0 Mar 25 15:03 cards
# -r--r--r-- 1 root root 0 Mar 25 15:03 devices
# lrwxrwxrwx 1 root root 5 Mar 25 15:03 Generic -> card1
# lrwxrwxrwx 1 root root 5 Mar 25 15:03 Generic_1 -> card2
# -r--r--r-- 1 root root 0 Mar 25 15:03 hwdep
# lrwxrwxrwx 1 root root 5 Mar 25 15:03 M2496 -> card0
# -r--r--r-- 1 root root 0 Mar 25 15:03 modules
# -r--r--r-- 1 root root 0 Mar 25 15:03 pcm
# dr-xr-xr-x 2 root root 0 Mar 25 15:03 seq
# -r--r--r-- 1 root root 0 Mar 25 15:03 timers
# -r--r--r-- 1 root root 0 Mar 25 15:03 version


pcm.!default {
    type hw
    card Generic_1
    slave dsp
}
ctl.!default {
    type hw
    card Generic_1
}



Run the grep and ls commands above to determine your card order. In this example ALSA script (thanks ALSA wiki) I set the card name "Generic_1" as 'default'. (M2496 is a add-on) If you save this example as '~/.asoundrc' and edit as needed it should work next time you login.

I tried tweaking the /etc/modprobe.d/alsa.conf to change card order as per the ALSA wiki. Though I could affect the order I just couldn't get the ALC892 as 'card zero'. Perhaps the presence of M2496 got in the way.

I haven't tried HDMI yet. Or SPDIF (iec958).

Great! Creating the ~/.asoundrc file with the entries you suggested solved the issue. I did not even have to log out to make it work. I did have to make a minor modification: the line:
slave dsp
was not accepted. I took this out and it worked!

I should also mention that the command "aplay -D default <some wave file>" helped me to find the issue in the ~/.asoundrc file:
Code:
aplay -D default test.wav
ALSA lib pcm_hw.c:1466:(_snd_pcm_hw_open) Unknown field slave
aplay: main:682: audio open error: Invalid argument



Thank you very much for your help!

Big OOps.. the erroneous 'slave dsp' line reminded me that I had problems opening more than one sound app (flash, mplayer, etc) at a time. I found a 'dmix' plugin example and added 'Generic_1'. This is my current .asoundrc file which allows me to have multiple sound apps open at the same time:

Code:

pcm.!default {
   type plug
   slave.pcm "dmixer"
}

pcm.dmixer  {
    type dmix
    ipc_key 1024
    slave {
      pcm "hw:Generic_1"
      period_time 0
      period_size 1024
      buffer_size 4096
      rate 44100
   }
   bindings {
      0 0
      1 1
   }
}

ctl.dmixer {
   type hw
   card Generic_1
}


Pardon my confusion.

Putting the entries in /etc/asound.conf produced the same result: sound works. Since the configuration is specific to the computer rather than the user, this is a much better way to configure it.

i can't get my sound working even after making a asounrc as shown above

may request OP to post kernel .config of the sound portions pls?
it may help me
