Hi all,
I have a problem when using ALSA lib . The problem is :
My ALSA driver only support a special sample rate , so ALSA lib must
convert sample rates. But My driver don't get any audio data. When
tracing the code of ALSA lib (alsa-lib-1.0.23), I found that : It mmap
a address from my driver , but writing audio data to another address
instead of that mmaped address.
I think this is why my driver don't get any audio data . But I don't know
why it don't write audio data to that mmaped address.
Can you help me ? Any advices would help me a lot.
Thank you,
longer.zhou
