[alsa-devel] alsaloop change avail_min question

[ed nwave]

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.
