Hello, I have a Philips SPC620NC webcam, connected via USB and using the uvcvvideo driver. Video is fine, but I can't get the internal microphone working. I have the needed USB sound modules loaded and I checked (hopefully correctly) with alsamixer that nothing is muted. arecord -l lists the device correctly, but when I make a test with arecord -vv -D default:1 test.wav I get a test.wav that contains no sound. Below you can see the output of the above command. System: openSUSE 10.3 with ALSA 1.0.14 running KDE with artsd Thanx a lot in advance for any hint Recording WAVE 'test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono Plug PCM: Rate conversion PCM (48000, sformat=S16_LE) Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : U8 subformat : STD channels : 1 rate : 8000 exact rate : 8000 (8000/1) msbits : 8 buffer_size : 2730 period_size : 170 period_time : 21333 tick_time : 0 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 170 xfer_align : 170 start_threshold : 1 stop_threshold : 2730 silence_threshold: 0 silence_size : 0 boundary : 178913280 Slave: Direct Snoop PCM Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 1 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 16384 period_size : 1024 period_time : 21333 tick_time : 0 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 1024 xfer_align : 1024 start_threshold : 6 stop_threshold : 16384 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Hardware PCM card 1 'USB Video Camera' device 0 subdevice 0 Its setup is: stream : CAPTURE access : MMAP_INTERLEAVED format : S16_LE subformat : STD channels : 1 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 16384 period_size : 1024 period_time : 21333 tick_time : 3333 tstamp_mode : NONE period_step : 1 sleep_min : 0 avail_min : 1024 xfer_align : 1024 start_threshold : 1 stop_threshold : 1073741824 silence_threshold: 0 silence_size : 0 boundary : 1073741824 Aborted by signal ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Register now and save $200.
