Hi,

is the ALSA-Lib-API thread-safe concerning the following scenario:


in thread 1 the audio-processing takes place via snd_pcm_avail_update(),

snd_pcm_begin(), snd_pcm_commit(). In thread 2 I call the functions:

snd_pcm_hwsync(), snd_pcm_avail_update() to get the actual delay via

bufferframes - snd_pcm_avail_update(). Should I lock these calls or

should I use instead snd_pcm_avail() in thread 2 ?

Is there any difference concerning thread-safety between the hw: layer or the plug: layer ?

Confused,

Ciao,

Daniel.
