I am also experiencing this identical problem although my southbridge is an 8233a it is identified as the 8233 doesn't play audio and goes through the files lightning fast. Responsible Changed From-To: freebsd-bugs->sound Another one for the sound guys. This problem is under investigation: patches are being exchanged with a couple of VT8233 owners and the relevant people at VIA have been contacted and asked for specs. Can you post details of the northbridge, KT333 or KT266, and what the output of 'pciconf -l' on the machine is? Thanks - Orion On Sun, 11 Aug 2002, Orion Hodson wrote:

The motherboard is an MSI KT3 Ultra with a VIA KT333 chipset.

The VIA VT8233 problem was caused by VIA changing the supported register sets between revisions of the VT8233 chipset. The driver was using the DXS registers, but these were (silently) killed off. After spending a fair amount of time exchaning patches to understand what had happened, Rafal Grzybowski spotted a comment explaining the issue in the ALSA source. Whilst VIA lose points for futzing with the spec, they gain some back for providing specs to make writing a new driver considerably easier. A driver relative to -stable today is available as a patch at: http://people.freebsd.org/~orion/stable-via8233.patch Apply with: cd ${SRC}/sys patch -p0 < stable-via8233.patch The driver still needs some work, but shouldn't cause any stability issues. Recording with a live sound sources is untested, and playback is not rigourously tested - playing some 8bit 8kHz audio files and some mp3's. If you test the driver as it stands now, I would appreciate the output of a verbose dmesg and your comments. Thanks - Orion State Changed From-To: open->closed Committed to -CURRENT, -STABLE, and due for inclusion in 4.7R. I was going to apply the patch in this PR (kern/38792) but then I saw that it was already added to 4.7-R: since I'm running that and still have this problem, I figured it might be worth a follow up. http://www.freebsd.org/cgi/query-pr.cgi?pr=44762 esd still causes this to be written to console: pcm0:play:0: play interrupt timeout, channel dead [/usr/src]# cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <CS461x PCM Audio> at irq 11 (1p/1r/0v channels duplex) [/usr/src]# grep pcm /var/run/dmesg.boot pcm0: <CS461x PCM Audio> on csa0 [/usr/src]# grep csa /var/run/dmesg.boot csa0: <CS4280/CS4614/CS4622/CS4624/CS4630> mem 0xf4000000-0xf40fffff,0xf4100000-0xf4100fff irq 11 at device 5.0 on pci0 csa: card is Thinkpad 600X/A20/T20 pcm0: <CS461x PCM Audio> on csa0 -- Paul Beard / 8040 27th Ave NE / Seattle WA 98115 / paulbeard [at] mac [ dot] com / 206 529 8400 weblog @ <http://paulbeard.no-ip.org/movabletype/> To generalize is to be an idiot. -- William Blake |
