[Alsa-user] No sound from X-Fi Xtreme Audio using ALSA version 1.0.20

[Peter D. <pet...@gm...>]

Hi.

I have a new Dell Inspiron and I am running Ubuntu Studio 9.10, 64bit.
 I cannot play any sound at all from the computer using Ubuntu.  The
dual-booted Windows 7 will play music files and all other sounds
without any trouble.

I've been working through troubleshooting procedures and searching the
web but I am not sure I am understanding the situation correctly or
which direction I should head.  Your advice would be much appreciated.

The sound card is a Creative Soundblaster X-Fi Xtreme Audio.  My web
searching seems to indicate that the card is not supported by ALSA.
However, it's not entirely clear to me because X-Fi in general is
supported.  Searching the web shows that some people have been able to
make the card work under Ubuntu but their solutions haven't worked for
me.

I have followed the troubleshooting steps at
https://help.ubuntu.com/community/SoundTroubleshooting#Basic%20Troubleshooting%20Steps.
 The codec for the soundcard is Creative CA0110-IBG which does not
appear in the ALSA-Configuration.txt for my ALSA version, 1.0.20
(http://tinyurl.com/yzmu498).  Since I didn't find what the correct
configuration for my card is, I did not alter the existing
configuration.

Also, the graphics card is listed as an audio device (ATI Technologies
Inc R700 Audio Device [Radeon HD 4000 Series]).  If I select this card
for sound output in the sound preferences control, there is still no
audio output.

Is this a situation in which I will need to replace the sound card?
Is there an alternate driver/configuration I should try for the X-Fi
Xtreme Audio?  Is there a different set of troubleshooting steps I
should work through?

Thanks for your help.  Any guidance will be very helpful.

Peter
