I’m running openSuSe 11.1 i586 GNOME, and I have been trying, unsuccessfully, to make my built-into webcam usb microphone to record something with 'arecord.
arecord -f cd -D hw:2,0 -d 20 test.wav
Recording WAVE ‘test.wav’ : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
arecord: set_params:966: Channels count non available
All my audio specs can be found here:
I’ve been following instructions from an Audacity Wiki:
USB mic on Linux - Audacity Wiki
In the process of doing this, I came across several issues about my sound card.
if I run the ‘speaker-test -c2 -l5 -twav’ I can hear the lady saying front left and right.
I tried the audio troubleshoot guide for OpenSuSe (SDB:AudioTroubleshooting - openSUSE), but I get to step 2:
Yast -> Hardware -> Sound and I try playing the test sound, NOTHING happens. I tried reconfiguring, either the quick setup and normal setup, but it made no difference.
If I do: cat /proc/asound/cards I get
0 [IXP ]: ATIIXP - ATI IXP
ATI IXP rev 2 with unknown codec at 0xc0003400, irq 17
1 [Modem ]: ATIIXP-MODEM - ATI IXP Modem
ATI IXP Modem rev 2 at 0xc0003800, irq 17
2 [U0x46d0x991 ]: USB-Audio - USB Device 0x46d:0x991
USB Device 0x46d:0x991 at usb-0000:00:13.2-1, high speed
It is the “ATI IXP rev 2 with unknown codec at 0xc0003400, irq 17” line that worries me. what is that about unknown codec? could it be that the reason of my mic’s failure?
Sometimes when I play a video on youtube.com, for example, I get a brief horrible noise at the beginning, but then I get normal audio (even though I run firefox from the terminal, I get no output concerning this issue).
I tried installing Skype to test my usb mic, but all I got was this
ALSA lib pcm.c:2202:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.hdmi
I was able to log into skype, but when I tried placing calls I got a “Problem with audio playback”. More puzzling is the fact that, after I rebooted, skype wouldn’t even start!
No protocol specified
I posted this problem on its own here: Skype fails to capture framerate (30), Unknown PCM cards - openSUSE Forums
But now, I have the feeling all these things are linked together. That’s why I posted this together.
I hope I get some responses
