 |
|
I'm failing to get a pair of Sennheiser PC36 headphones/mic running under ALSA.
I believe I have all of the necessary modules built into the kernel:
| Code: |
wombat linux # grep SND_USB .config
CONFIG_SND_USB=y
CONFIG_SND_USB_AUDIO=y
|
The headset is detected as a USB device:
| Code: |
wombat linux # lsusb

Not sure why it doesn't show up here:
| Code: |
wombat ~ # cat /proc/bus/usb/devices
cat: /proc/bus/usb/devices: No such file or directory
wombat ~ #
|
Seems to be detected:
| Code: |
wombat ~ # cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7e00000 irq 49

I checked to make sure nothing was muted in:
| Code: |
wombat ~ # alsamixer -c 1
|
And moved everything into the white.
When I try (talking into the mic).
| Code: |
arecord -f cd -D hw:1,0 -d 5 test.wav
|
Sometimes, I get file with no content.
Sometimes I get:
| Code: |
$ arecord -f cd -D hw:1,0 -d 5 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
arecord: set_params:1087: Channels count non available
|
The headset can also be used with the normal audio jacks (USB is through an adapter) and it works when connected that way so I don't think it is a broken hardware issue.
Any ideas? |
