  Hi

 I have this PCI soundcard (from "Encore" manufacturer)  and I am using
 debian lenny

 lspci | grep audio
 01:09.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24
 [Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01)

 I cant get sound of the 2 channels using neither an old 2.6.18 kernel or
 a new 2.6.32 from Debian or a 2.6.29 from Musix.

 There is no problem with the physical output jacks: all headphones play
 only one channel.

 Also i tried with all the mixers: alsamixer, gamix, gnome-alsamixer,
 kmix, etc. enabling and disabling all the things and it does not work
 well. 
 I recall a similar problem on a Debian system once, with my Audiophile
 2496 (same chipset). I think I resolved it simply by installing
 alsa-tools-gui and using the Envy24 Control mixer.  

Thanks for your help, but I tried it before and envy24 control said:

no ice1712 cards found

what could i do?

Thanks in advance

...
  It may have been a 
 matter of the correct volume controls not showing in the alsa mixers.
 Although the Envy24 Control mixer did not seem to function completely
 logically, I did manage to get satisfactory stereo output.

 Cheers
