Hello,

I am doing MMAP-based full duplex audio processing. I looked at the direct_loop code in the alsa-lib/test/pcm.c example. 

Now I want to run do the audio processing asynchronously. The async_direct_loop in the example does this, but I was wondering: is there any advantage to using snd_async_add_pcm_handler over using a simple pthread?

Thanks,

Maarten

No; the async handler is neither portable nor recommended.
That test program ist just for testing the API.
