Re: Compiling ALSA-Lib using uClibc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have found what is causing the problems : 
1)Udev does not create /dev/snd and /dev/dsp files, it does however
create /dev/pcmC0D0c and pcmC0D0p.
Why is that?


2)After I create the dev files manually all  the sound channels  are
muted by default.
How can I change that?


Thank you.
