Hello!
I have a Creative's sound-card (SB1040 PCI-Express), recognized as:
hdac0: <Generic High Definition Audio Controller> mem
0xd5efc000-0xd5efffff irq 18 at device 0.0 on pci10
hdac0: HDA Driver Revision: 20100226_0142
hdac0: [ITHREAD]
mixer reports:
Mixer vol is currently set to 70:70
Mixer pcm is currently set to 76:76
Mixer line is currently set to 90:90
Mixer rec is currently set to 75:75
Recording source: line
/dev/sndstat says:
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA Unknown Codec PCM #0 Analog> (play/rec) default
pcm1: <HDA Unknown Codec PCM #1 Analog> (play/rec)
pcm2: <HDA Unknown Codec PCM #2 Digital> (play/rec)
It works fine for sound reproduction, but I can't figure out, how to
make it work with the microphone...
When I start skype and make a call to their "Call Testing Service", I
see the following error on Skype's stderr:
RtApiOss: callback thread error (RtApiOss: audio read error for
device (/dev/dsp).) ... closing thread.
which coincides with the following kernel message:
pcm0: chn_read(): pcm0:virtual:dsp0.vr0: record interrupt timeout,
channel dead
or, after I set dev.pcm.0.rec.vchans=0:
pcm0: chn_read(): pcm0:record:dsp0.r0: record interrupt timeout,
channel dead
I'd appreciate any hints -- I run 8.2/amd64 as of Feb 21st. Thanks!
Yours,
-mi
