Yes, a pipeline with only one alsa module can failed. This is something I've
noticed several times.
IRL, I rarely pipeline alsasrc to alsasink, and it failed every day (I use a
cron to relaunch the pipeline before failure :D ). The "alsasrc ! alsasink"
pipeline is just "one of pipeline known to fail", and the easiest to reproduce.
For your information, I have an "audiotestsrc ! alsasink" pipeline running
since three days without problem.
The problem seems appear when connectig one live source to a live sink, if one
of this live source or sink is an alsa module (audiotesrsrc is an exception
since it has been conceived to handle every usecase).
does'not fail:
jackaudiosrc ! something ! jackaudiosink
jackaudiosrc ! something ! opusenc ! rtpopuspay ! udpsink
udpsrc ! rtpopusdepay ! rtpjitterbuffer ! opusdec ! something ! jackaudiosink
fails:
alsasrc ! something ! alsasink
jackaudiosrc ! something ! alsasink
udpsrc ! rtpopusdepay ! rtpjitterbuffer ! opusdec ! something ! alsasink
Today I don't know if the alsasrc module can't fail at all.
I knew it, but I do not know now. I think it can fail too.
This time, the "jackaudiosrc ! something ! alsasink" pipeline had failed in
less than 14 hours, sometimes it fails in more than 20h.
Perhaps alsasrc can fails with more time.
It seems to me that if I wait long enough, I have to restart both "alsasrc !
something" and "something ! alsasink" pipelines.
