+++ This bug was initially created as a clone of Bug #911777 +++

CUBEB_STREAM_MAX in cubeb_alsa is half what it is in cubeb_winmm.
It's restricted in cubeb_winmm to avoid what appears to be an OS issue: bug 742154.

It's less in cubeb_alsa because the alsa-pulse plugin causes a 64MB mapping to be created per PCM, so 16 is already 1024MB.  That's avoidable by doing the last bits of work to enable PulseAudio by default on Linux: bug 837563.

Do we still care about this?

I don't but maybe other people care? We don't use Alsa by default these days, but it's still supported.
Priority: -- → P4
With multiple AudioContexts mixed into one stream (and with close on page unload) now, this is no longer an issue for Web Audio.

I guess now that alsa is only used when pulseaudio is not available, the alsa-pulse plugin won't be involved, so perhaps there is no longer the need for such a limit with alsa, but this doesn't seem very important now.

Mass change P4->P5 to align with new Mozilla triage process.
Priority: P4 → P5
No longer relevant for Gecko, as it no longer uses cubeb_alsa.
