I can mix as many streams as I want using just "aplay" but if I start by playing one track with "ogg123" (which uses a default, unconfigured libao as its backend), I can't start a second ogg123, which then says:
ao_alsa WARNING: Unable to open surround playback. Trying default device...
The default dmix is for stereo only. For a surround dmix device, you'd have to write your own definition.
Thank you. I didn't notice it was related due to the "trying default device" which I thought should've worked but the issue is that libao 1.1.0 doesn't use the alsa "default" device by default. The first ogg123 instance therefore keeps things busy.
There's a matching bug-rapport here, I see:
https://trac.xiph.org/ticket/1776
I can, now, set it to dev=default manually but what this means is that libao-1.1.0 by default kills alsa default software mixing. These days everybody seems to have regressed to using a soundserver again anyway and as such not many may notice, but this izz no good, I feel... :-/
In any case, hope this was useful to alsa-devel in the sense that this libao behavior is now known here, but this is otherwise libao related only, then.
