hi,
um ....how do i extract the audio buffers from
memory inside say a card driver, like the snd-dummy. i am just
experimenting with ALSA to see if it is possible to stream the audio data to the
1394 bus...
so i just need to know how to get the data out
of the buffer...
i assume a call to this gets the size
out:
snd_pcm_lib_buffer_bytes(substream);
what pcm_function will return the *buffer? do i access it through runtime->dma_area?
thanx,
john.
