Re: [alsa-devel] Question about the buffer length in the transfer callback of the PCM External Plugin

Ok, what about the output buffer?

"Output" from which point of view? Playback or capture?

When just 960 bytes are ready to be returned but I have to return 1000 bytes?

In theory, this is an underrun.

You could wait until the next 40 bytes are available.
