Hello there.
I tried to run a number of SIP softphones (linphone, kphone, etc), and
just found out my problem was the mic recording device, and not the SIP
software.
I tried to make basic testings on recording, copying from
/dev/audio|/dev/dsp to a file or to /dev/dsp as output. Every single
test returns the same:
pcm0:record:0: record interrupt timeout, channel dead
Tried in both 5.4-S and 6.0-CURRENT (from Jun 8th). Any idea what is
causing this? And how to fix it?
Hardware identifying:
(eksffa@claire-redfield)~> grep "snd\|sound" /sys/i386/conf/CLAIRE
device sound
device "snd_t4dwave"
(eksffa@claire-redfield)~> cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Acer Labs M5451> at io 0x8800 irq 11 (4p/1r/0v channels duplex
default)
(eksffa@claire-redfield)~> pciconf -lv | grep -B4 audio
pcm0@pci0:4:0: class=0x040100 card=0x8158104d chip=0x545110b9 rev=0x02
hdr=0x00
vendor = 'Acer Labs Incorporated (ALi)'
device = 'ALI M5451 PCI AC-Link Controller Audio Device'
class = multimedia
subclass = audio
(eksffa@claire-redfield)~> grep -i pcm /var/run/dmesg.boot
pcm0: <Acer Labs M5451> port 0x8800-0x88ff mem 0xf0401000-0xf0401fff irq
11 at device 4.0 on pci0
pcm0: <Analog Devices AD1981B AC97 Codec>
pcm0: [GIANT-LOCKED]
O also tried to set sc->duplex = 1 on /sys/dev/sound/pci/solo.c (around
line 972) but it caused my output device to not work properly as it does
when sc->duplex = 0 and the mic device still did not work anyway.
Thanks :-)
