[alsa-devel] DELL SP2309W Monitor with Integrated microphone
Any luck anyone with this one yet? I too have the same issue as that posted previously (last month), and get the same results with the indicative testing. I have tried several fixes via googling - module loading and sound "card" indexing via alsa.base modprobe file and LOTS of others. Still no luck. I am running FC10 with pulse, but think it's probably a snd-usb-audio problem as the driver appears to be correctly loading and the webcam is clearly indicated in the sound prefs app and gconf/gstreamer. I have run thru the usb audio device classes, and all of the reported class values reported via lsusb -v seem to correctly correspond to possible values from the audio class parameters. I'm now stumped. I do get the following errors in the gnome sound recorder: "Could not negotiate format" followed by "Could not get/set settings from/on resource.". This jives with the error from the sound preference panel: "gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat: Could not get/set settings from/on resource." which does not reveal anything specific enough to track down the problem from searching the net. All other sound devices and services are performing correctly via pulseaudio. I have at one time removed p/a, but this did not correct the problem. I am running the webcam mic as device 0, but changing that to any other device number fails to solve the problem. Alsamixer shows the card "Monitor Webcam" mic, the chip "USB mixer", the recording levels at 74, the capture enabled, and the AGC and loudness parameters enabled, and although I have tried various combinations of these, none have worked.
I am running version 1.0.19 of the alsa drivers, and compiled these directly with all everything enabled as well as using the rpm builds. Alsainfo has been uploaded to:
http://www.alsa-project.org/db/?f=803829378929c58bcc86351c091719a12c79075e
The video portion of the camera functions entirely correctly via uvc and v4l, but the audio listing from the video test app gucveiw does not list the webcam mic at all under the audio device list. The uvc dev group sent me here, naturally.
Cheers, PG

Try disabling pulse and run:
arecord -v -f cd -D plughw:0 file.wav
Does file.wav contain any audio? What does arecord output?

I get:
"arecord -v -f cd -D plughw:0 file.wav Recording WAVE 'file.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo ALSA lib pcm_params.c:2135:(snd1_pcm_hw_refine_slave) Slave PCM not usable arecord: set_params:939: Broken configuration for this PCM: no configurations available"
To disable p/a, I selected alsa in all sound prefs. The ALSA webcam driver is also selected for "sound capture". I then did "sudo killall pulseaudio" as well as "pulseaudio -k" for root (sudo) and normal user.
A file.wav was not created.
