audio playback slow
I just setup FreeBSD 5.0-CURRENT as of last night on my system. I setup the pcm driver and it detected my onboard VIA audio (at least partially), however playback is at about half speed. I am basically running GENERIC with the debug options commented out and device pcm added. I suspect it might be because of the AC97 Codec message, but I do get playback, just slowed down. -Wade - Some bits from dmesg: pcm0: VIA VT8233A port 0xe000-0xe0ff irq 12 at device 17.5 on pci0 pcm0: Unknown AC97 Codec (id = 0x414c4730) Some bits from pciconf -l -v: [EMAIL PROTECTED]:17:5: class=0x040100 card=0x47304005 chip=0x30591106 rev=0x40 hdr=0x00 vendor = 'Via Technologies Inc' device = 'VT8233/33A AC97 Enhanced Audio Controller' class= multimedia subclass = audio To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message

Wade. The AC97 codec message is unrelated, it's just a missing/mis-entered codec id, it's an ALC101. This should now be fixed in the repository. I believe the speed problem lies with the driver mis-reporting of capabilities of the chipset when the ac97 codec does not support on-chip sample rate conversion which the ALC101 does not. Again, this should now fixed in the repository. If you can update and let me know. Should it fail, can you set 'sysctl hw.snd.verbose=3', 'cat /dev/sndstat' while playing the offending audio, and send me the output.

Re: audio playback slow
The AC97 codec message is unrelated, it's just a missing/mis-entered codec id,

That message does appear to be fixed now, it reports:
pcm0: Avance Logic ALC101 AC97 Codec
I believe the speed problem lies with the driver mis-reporting of capabilities
of the chipset when the ac97 codec does not support on-chip sample rate
conversion which the ALC101 does not. Again, this should now fixed in the
repository.
I am still getting slowed down playback :( Here is the output you
requested. I didn't think the fileversions were important here.

Hope this helps.
