Rene: I modprobe em28xx-audio after plug in the stick and here is the pertinent dmesg output:
em28xx-audio.c: probing for em28x1 non standard usbaudio em28xx-audio.c: Copyright (C) 2006 Markus Rechberger Em28xx: Initialized (Em28xx Audio Extension) extension After that I did a ls /dev/dsp* and here is the output: /dev/dsp /dev/dsp1 After that, since I see /dev/dsp1 I did the following sox command: sox -r 16000 -w -c 2 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp I received the following output: Input File : '/dev/dsp1' (ossdsp) Sample Size : 16-bit (2 bytes) Sample Encoding: signed (2's complement) Channels : 2 Sample Rate : 16000 The I started tvtime with good video, but no sound, and after a few seconds I received the following output in the console where I sent the sox command: sox sox: /dev/dsp1: Premature EOF while reading sample file. (Input/output error) Again, than you in advance for your valuable help, I think that now we are very close to get sound but maybe this are not the right sox parameters.
