[alsa-devel] alsaloop change avail_min question
Hi,
Over time I see the message below and the value slowly creeps up. Is this a simple information output or more of a warning? If run alsaloop for a long time - many hours of music, will alsaloop be prone to failure because of this value increasing?
playback plughw:Siso: change avail_min=7299
Thanks.

It's difficult to say without knowing the details (the used parameters). The avail_min increase was added to avoid "no wait" loop (100% CPU usage).

OK, next time it does it I will post the parameters. The CPU usage is very low for 44100 alsaloop in general. For future reference what does the avail_min do/represent? Knowing what this value does may help next time it occurs.
Thanks.
