Hi Guys,

I'm completely new to Linux and I'm having a good deal of difficulty getting the Wolfson DAC (among other things) to work. I am running Ubuntu 5.04.

As of right now, I can get the normal line out(green jack) working with OSS. However, when I select ALSA in XMMS, it gives me some error about device cannot be found or something like that. And when I look at the alsamixer, it displays the mixer for my nforce onboard sound, rather than the AV710 chip (starts with "ICE" I believe?)

So would someone mind walking me, STEP-BY-STEP (as I'm completely new to all of this) to get the Wolfson DAC working? I never thought I'd have to do so much work to get things I take for granted on Windows to run.

Thank you

Try the following.
Code:

Code: 
[left]aplay -D default yourMusic.wav[/left]

Does that work?
Now try.
Code:

Code: 
[left]aplay -D hw:0,0 yourMusic.wav[/left]

post the outputs you get.

Hi blueworm

Thank you for your help. I get the same output for both of the lines you posted:

Code:

Code: 
[left]Playing WAVE 'FunkMusic.wav' : Unsigned 8 bit, Rate 11025 Hz, Mono aplay: set_params:857: Sample format non available[/left]

Same thing happens when I try a mp3.

Do the following.
edit your .asoundrc so it looks like this.
Code:

Code: 
[left]pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }[/left]

now repeat.
Code:

Code: 
[left]aplay -D default yourMusic.wav[/left]

If that does not produce sound and an output like this re-install the latest drivers alsa 1.0.9b.
Code:

Code: 
[left]aplay -D default foo.wav Playing WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo[/left]

If that works we will be able to move on to try get the rear channels to work.

Ok done, even though alsamixer still shows the nforce2...

Ok here I am confused. I have no such asoundrc in any relevant directory. I have asound.rc in /usr/share/doc/jackd/examples. Are you sure you are not referring to asound.conf and asound.state in my /etc/ directory? (I also have an asound.state in my /var/lib/alsa directory) I tried modifying asound.conf with what you said but I still get the same error so I reverted back to my original asound.conf.

alsamixer should not show nforce2!
what do you get if you do?
Code:

Code: 
[left]alsamixer -c1[/left]

Also do Code:

Code: 
[left]lsmod[/left]

and post the read out.

Alsa works like this. it reads a list of rules in /etc asond.conf and applies them to all the users, BUT if a particular user has a .asoundrc (note the period before asoundrc, this denotes a hidden file) this will take presedence. These rules are in turn defined by /usr/share/alsa/alsa.conf .

Hmm ok. Well I made an .asoundrc file and dropped it into my home directory and pasted what you posted in your first post. I still get the same error though (even after a reboot)

Here is my /proc/asound/cards if it helps at all..

Code:

Code: 
[left]0 [nForce2 ]: NFORCE - NVidia nForce2 NVidia nForce2 with ALC655 at 0xef002000, irq 21 1 [AUDIO2000 ]: ICE1724 - AMP Ltd AUDIO2000 AMP Ltd AUDIO2000 at 0x9000, irq 16[/left]

I tried modifying that file and remove the nforce...but it didn't let me...even when I used the sudo command...

Now try this
Code:

Code: 
[left]aplay -D hw:1,0 yourMusic.wav[/left]

That should be front 2 channels.
If that works try.
Code:

Code: 
[left]aplay -D hw:1,2 yourMusic.wav[/left]

That should be rear 2 channels.

post what you have in /etc/modules.d/alsa.
Or simply run.
Code:

Code: 
[left]alsaconf[/left]

And configure only the ice1724 card.
