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. /************ Output of aplay -L ****************/aplay -Ldefault:CARD=Intel HDA Intel, CA0110 Analog Default Audio Devicefront:CARD=Intel,DEV=0 HDA Intel, CA0110 Analog Front speakerssurround40:CARD=Intel,DEV=0 HDA Intel, CA0110 Analog 4.0 Surround output to Front and Rear speakerssurround41:CARD=Intel,DEV=0 HDA Intel, CA0110 Analog 4.1 Surround output to Front, Rear and Subwoofer speakerssurround50:CARD=Intel,DEV=0 HDA Intel, CA0110 Analog 5.0 Surround output to Front, Center and Rear speakerssurround51:CARD=Intel,DEV=0 HDA Intel, CA0110 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakerssurround71:CARD=Intel,DEV=0 HDA Intel, CA0110 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakersiec958:CARD=Intel,DEV=0 HDA Intel, CA0110 Digital IEC958 (S/PDIF) Digital Audio Outputhdmi:CARD=Intel,DEV=0 HDA Intel HDMI Audio Outputnull Discard all samples (playback) or generate zero samples (capture)
