Re: [alsa-devel] Should snd_pcm_drop() interrupt snd_pcm_writei() call?

...

This explains the problems I encountered. I missed the information, that these functions are not meant to be thread-safe.

Although it's not recommended, the behavior you described sounds strange. Could you check whether this still happens with the very latest alsa-lib version?

Yes, we will try to, but I need some cooperation with colleague, so it will take some time.

Also I guess this depends on the plugin to be used, e.g. dmix or not.

I see. Please, can you tell me, whether I should rewrite my program to purely single-thread acces to snd_pcm_write & snd_pcm_drop, or should I expect, that in ALSA (with proper plugin) it should work in correct releases?

Thank you for your answers, Marek.
