Envy24HT mixer restore problem with M-Audio Revolution 7.1 + Alsa 1.0.4

Envy24HT mixer restore problem with M-Audio Revolution 7.1 + Alsa 1.0.4

[Stephen Hassard]

Hi there,

I've got an Envy24HT based M-Audio Revolution 7.1 and have a issue with 
Alsa 1.0.4.

When I set my 'DAC' and 'DAC1' channels to sane values (they correspond 
to L+R audio) and save my mixer settings via 'alsactl store', reboot and 
restore the settings via 'alsactl restore', my mixer settings appear to 
be normal in alsamixer, but I find that my left channel ('DAC') is 
mutted until I change the volume of 'DAC'. As soon as I touch the mixer 
for the 'DAC' channel, audio output is restored.

I didn't notice this a few revisions back, so I think a bug crept in 
recently ..

Thanks,
Steve

Interesting. I 'll see what I can do since I have a pretty similar card 
(Audiotrak Prodigy 7.1).

Can you try changing the line:
    change = (ovol != nvol);
to
    change = 1;

in file aureon.c (in alsa-kernel directory) functions wm_dac_vol_put & 
wm_adc_vol_put (the first one should really be enough in your case).
You could also try to see if the problem persists after unloading and 
reloading the snd-ice1724 module to avoid rebooting.

I have the exact same problem with a TerraTec EWX 24/96 (ice1712 AKA not HT 
Envy24), though on the right channel. In my case this is a long lasting 
quirk (easy to solve with a simple amixer call), cause it's there since at 
least 0.9.0. I also checked the driver code sometimes sgo but haven't been 
able to find any problem in the code.

Bye,
