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-driver-1.0.23), I found that : It mmap a address from my
driver , but writting 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 audo data to that mmaped address.
Can you help me ? Any advices would help me a lot.
Thank you,
longer.zhou
