Marketing info is this is an "nForce410" board, with "6-channel HD audio". Both the ALSA in 2.6.15-rc6-git4 and the 1.0.11rc1 ALSA driver for snd-hda-intel load fine, but during playback, the left channel squeals, while the right seems to play things okay. I'm happy to dig around and try whatever needs trying to get this fixed. Thanks! ====================================================================== ---------------------------------------------------------------------- kees - 12-26-05 11:02 ---------------------------------------------------------------------- If I do "speaker-test -c4", both front channels work fine. "speaker-test -c2" fails as above: single tone (or silent) on left channel, right channel is okay. Strangely, if I use the rear mobo line out jack (instead of the front-panel headphone jack), "speaker-test -c4" fails on the left channel too. Very odd. And, "speaker-test -c6" doesn't even run. It bombs out with errors: 0 - Front Left Write error: -5,Input/output error xrun_recovery failed: -5,Input/output error Transfer failed: Operation not permitted ---------------------------------------------------------------------- morgoth666 - 12-30-05 23:50 ---------------------------------------------------------------------- Hi all Just for completeness: I have the same problem on ASUS A8N-VM-CSM mobo (with AD1986A chip), kernel 2.6.15-rc7, alsa CVS downloaded on Dec,30 2005. my lspci gives the same as in previous note (with more capabilities !): 0000:00:10.1 0403: 10de:026c (rev a2) Subsystem: 10de:cb84 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 5 Memory at febd8000 (32-bit, non-prefetchable) [size=16K] Capabilities: [44] Power Management version 2 Capabilities: [50] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable- Capabilities: [6c] #08 [a802] It seems that the problem is related to surround sound: see a quick workaround here => http://www.nabble.com/Intel-HDA-AD1986A-without-surround-t595968.html Hope this helps !
