Audio play too fast on AC97 onboard
Hello
I noticed it with OpenBSD 3.4 & it didn't change up to 3.7.
I didn't report that because i din't use sound so much before 3.7.
Now i'm using OBSD much more so sound start to be important for me:)
First of all, the audio play too fast. I searched on mailing list archives,
& i find that it's nothing new because some audio chips works with 48000Hz.
The solution was to set playing rate to 44100 with "audioctl".
So this is what "# audioctl -a" gives me:
name=VIA VT82C686A
version=
config=auvia
encodings=ulinear:8,mulaw:8*,alaw:8*,slinear:8*,slinear_le:16,ulinear_le:16*,slinear_be:16*,ulinear_be:16*
properties=full_duplex,mmap,independent
full_duplex=0
fullduplex=0
blocksize=9600
hiwat=6
lowat=1
monitor_gain=0
mode=
play.rate=48000
play.channels=2
play.precision=16
play.encoding=slinear_le
play.gain=127
play.balance=32
play.port=0x0
play.avail_ports=0x0
play.seek=9600
play.samples=26874240
play.eof=0
play.pause=0
play.error=1
play.waiting=0
play.open=0
play.active=0
play.buffer_size=65536
record.rate=48000
record.channels=1
record.precision=8
record.encoding=mulaw
record.gain=191
record.balance=32
record.port=0x1
record.avail_ports=0x7
record.seek=0
record.samples=0
record.eof=0
record.pause=0
record.error=0
record.waiting=0
record.open=0
record.active=0
record.buffer_size=65536
record.errors=0
I try to make "# audioctl play.rate=44100" but the answer was:
audioctl: set failed: Invalid argument
I read that sometimes even witht hat notice it is working. But not thios time.
Play rate is still 48000.
Another intresting thing is that sometimes i get notice on terminal like this:
"auvia0: codec invalid".
Here is my dmesg:
