Ok! I did it. *The good news*:
Building "sound-unstable-2.6.git" with kernel 2.6.26.3 made the VT1708B
chip on my ASUS-M3N78-VM flawlessly working (at least I don't hear
distortion).
The alsa parts in
(1) the kernel SUSE 11.0 ( 2.6.25.11-0.1-default)
(2) the latest stable version 2.6.26.3 as well as
(3) the alsa-driver-1.0.18rc1
made a lot of distortion. You could stand it for a while listening to
48kHz (DVB and DVD), but it was terrible with 44,1kHz (Wav files and CD).
The distortion with the VT1708B was actually the reason buying the
Creative X-Fi Xtreme Audio PCIe card.
*The bad news:*
The PCIe card does not work. The driver "snd_hda_intel" loads fine, but
when running
aplay -Dhw:0,1 /usr/share/sounds/alsa/test.wav
->Playing WAVE '/usr/share/sounds/alsa/test.wav' : Signed 16 bit
Little Endian, Rate 44100 Hz, Stereo
the output 10s later is:
->aplay: pcm_write:1394: write error: Eingabe-/Ausgabefehler
(Translation: Input-/Output Error)
According to /proc/interrupts, there are approx. 10 interrupts while
playing "test.wav".
But there is no sound at the front speaker-output. I haven't tested the
optical SPDIF output yet, but will do so the next week.
No log in /var/log/messages.
Prior to doing the tests and creating the logs I disabled the VT1708B
in the BIOS. Therefore it is not listed below.
