Hi,
Thank you very much for providing sound support on the High
Definition Audio Controller, and for your help on IRC.
Here is my environment:
$ uname -a
FreeBSD zoupla.cottages 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #0: Fri Dec 15 23:24:25 CET 2006 jbq@zoupla.cottages:/usr/obj/usr/src/sys/GENERIC amd64
$ pciconf -lv | grep -B 4 multimedia
^^^^^^^^^^ NOTE that I replaced audio
with multimedia!
class = bridge
subclass = PCI-PCI
pcm0@pci0:16:1: class=0x040300 card=0x01ed1028 chip=0x026c10de rev=0xa2 hdr=0x00
vendor = 'NVIDIA Corporation'
class = multimedia
$ sysctl hw.snd
hw.snd.latency_profile: 1
hw.snd.latency: 5
hw.snd.report_soft_formats: 1
hw.snd.feeder_buffersize: 16384
hw.snd.feeder_fmt_downmix: 0
hw.snd.feeder_rate_round: 25
hw.snd.feeder_rate_max: 2016000
hw.snd.feeder_rate_min: 1
hw.snd.verbose: 1
hw.snd.sndstat_isopen: 0
hw.snd.maxautovchans: 4
hw.snd.default_unit: 0
The result is a half-success: sound output works fine, but sound
recording has a weird sample rate, like two times slower than
normal. Also note that with the rear sound panel, recording does
not work at all.
Any input will be appreciated. Thanks in advance,
