Hi!
I wanted to know the state of the pcm driver regarding the AWE64 sound
card. At least there is no panic anymore:
anarcat@shall [anarcat]$ rec -w -r 44100 file.wav
Send break (control-c) to end recording
^CTerminated
I had to kill the process from outside and still had:
pcm0: record overrun, dumping 88876 bytes
messages..=20
What is odd is that other tools do not necessarly have the same behavior
as sox. Ecasound (audio/ecasound port) for example, records fine. Try:
ecasound -c -i:/dev/dsp -o:test.wav
and then type "run". It will record audio in a 16 bit 44100 Hz file.
Though I'm not sure it's not undersampled or something at the kernel
level. How can I tell if the sound was really recorded in 16/44100?
Does anyone know if the same happens under a Sound blaster 16C?
Here is my dmesg, and thank you for any help:
