Public bug reported: Pulseaudio 4.0 has a limit of 32 simultaneous streams, which may be multiple instances of music/video players or multiple browser tabs. If this limit is reached it is not obvious what is going on, there may be a wrongly-worded error message like 'Init failed: Too large', it may cause significant problems, or the unexpected resumption of audio hours or days later without it being obvious where it is coming from, and in one case seemed to mess up alsa requiring a reboot.
This limit is unnecessary and has already been fixed in pulseaudio 5.0. Please backport this change, which is only a single number, to Ubuntu 14.04 LTS, so that these failures no longer occur. The proposed single number change: http://pulseaudio-discuss.freedesktop.narkive.com/3jsDewHK/patch-sink-increase-max-sink-inputs-per-sink A recent version of the file including the change: https://github.com/otcshare/pulseaudio/commits/master/src/pulsecore/sink.h The pulseaudio 5.0 release notes saying the change was included there: http://www.freedesktop.org/wiki/Software/PulseAudio/Notes/5.0/ "sink: Increase max sink inputs per sink" The change is in pulsecore/sink.h -#define PA_MAX_INPUTS_PER_SINK 32 +#define PA_MAX_INPUTS_PER_SINK 256 ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1492404 Title: Backport limit increase for pulseaudio number of streams Status in pulseaudio package in Ubuntu: New Bug description: Pulseaudio 4.0 has a limit of 32 simultaneous streams, which may be multiple instances of music/video players or multiple browser tabs.
