Hi Georg,
I was working on simple Openwrt Platform, and Source device is
Android phone Bluetooth with Youtube app 24 hrs live streaming video
and alsa device is speaker, which is hardwired
The 12 hrs testing which i did on pulseaudio-11.1 are without my
modification. The basic modification which i made in the previous
pulseaudio-8.0 is with the idle state of bluez_source card (i.e.,
card is vanishing when the song is in the pause state) and did some
changes to buffers of pulseaudio to reduce the latency. But in
pulseaudio-11.1 i didn't do all the changes as i didn't find any
initial latency. but periodic latency after 12hrs still exists. The
issue is reproducible with Gstreamer also.
I haven't worked on microphone scenarios, I'm just working on music
player and speaker.
Let me clear you some test scenarios for better understanding,
Case 1: Android phone as source (bluez_source) and device with
internal speaker (alsa-sink as sink for pulseaudio) -------> delay
after 12hrs exists.
Case 2: Device with Gstreamer as source and same device with internal
speaker (pulsesink with alsa card as sink for pulseaudio) ---------->
delay after 12 hrs exists.
Case 3: Device with Gstreamer as source and External Bluetooth
speaker (pulsesink with bluez_sink card) -----------> No delay after
12 hrs.
What output does module-loopback give when you run with debugging?
Do you see the growing latency there? Does it show up with pactl list
sinks
or pactl list sources? Any error messages in the PA log?
Regards
Georg
One more comment: It may well be worth trying 12.2 because the bluetooth
thread
function has changed.
