Bug#755270: No sound output, ALSA lib ... Unknown PCM

[Eduard Bloch]

Package: qutecom
Version: 2.2.1+dfsg1-5+b2
Severity: normal

Hi,

I have used qutecom for a while but now it started failing. It's
supposed to use a headset attached through internal USB audio
converter. The menus display the hadware correctly but clicking the Test
button only produces the message below (straced). As ringing device, an
onboard soundcard output is configured, which works fine.

Please advise how to continue investigating this.

[pid 11780] stat("/usr/share/alsa/alsa.conf", {st_mode=S_IFREG|0644, st_size=9316, ...}) = 0
[pid 11780] write(2, "ALSA lib pcm.c:2239:(snd_pcm_ope"..., 44) = 44
[pid 11780] write(2, "Unknown PCM ", 12) = 12
[pid 11780] write(2, "\n", 1)           = 1
