|
~~~~~~~~~~~~~~~~~
|
||||||
|
Sound is supported by the ALSA driver: snd_usb_audio
|
||||||
|
|
||||||
|
One 16-bit channel with sample and playback rates of 8000 Hz is the practical
|
||||||
|
limit of the device.
|
||||||
|
|
||||||
|
Example - recording test:
|
||||||
|
arecord -v -d 10 -r 8000 -f S16_LE -t wav foobar.wav
|
||||||
|
|
||||||
|
Example - playback test:
|
||||||
|
aplay foobar.wav
