Hello!
I have a Logitech's webcam with built-in microphone. The audio device is
recognized by FreeBSD-8-stable as:
uaudio0: <vendor 0x046d product 0x081b, class 239/2, rev 2.00/0.10,
addr 2> on usbus2
uaudio0: No playback!
uaudio0: Record: 48000 Hz, 1 ch, 16-bit S-LE PCM format
uaudio0: No midi sequencer
pcm1: <USB audio> on uaudio0
mixer(8) reports it a little strangely, depending on which /dev-entry I
use:
% mixer -f /dev/mixer1
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
% mixer -f /dev/dsp1
Mixer rec is currently set to 45:45
But recording works. For example, using the rec-utility from the SoX
package:
% env AUDIODEV=/dev/dsp1 rec /tmp/test.aiff
Input File : '/dev/dsp1' (ossdsp)
Channels : 2
Sample Rate : 48000
Precision : 16-bit
Sample Encoding: 16-bit Signed Integer PCM
Well, it almost works, because the recording ends up highly distorted --
much faster, than what I'm really saying into microphone. About three
times faster. For example, if I let the above command run for 18 seconds
(according to time(1)), the created test.aiff will contain a 6-seconds
recording.
How do I fix this? Thanks! Yours,
-mi
