Hi Alexandre,
I did your test, I don't see a pause cycle when I have firefox play a video.
I do get those messages every time there is an audio glitch. At some times
with chromium open I will get far fewer of these messages but no interrupt.
When I say far fewer, I mean I could maybe get 1 of those messages at any
given time but no interruption. With Firefox, all these outputs are from me
opening sites in a couple tabs. This is the output I get when I run audio in
firefox from start to stop:
snd1 pst=ini: device started
snd1 pst=run: started
firefox0 vol=127,pst=rdy: attached at -7680 + 0/480
firefox0 vol=127,pst=rdy: set weight: 8388608/8388608
snd1 pst=run: play hw xrun, pused = 6240/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6240/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6240/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6240/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6240/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
snd1 pst=run: play hw xrun, pused = 6720/7680
snd1 pst=run: play hw xrun, pused = 7200/7680
firefox0 vol=127,pst=run,rmsg,widl: STOP message
firefox0 vol=127,pst=run: stopping
firefox0 vol=127,pst=ini,rmsg,widl: stopped
So the behavior is the same whether I play audio IN Firefox or
outside of Firefox. any opening of tabs or doing something from within
a website that may require loading data will cause any audio
to stutter. Sometimes even simply having firefox running in the background
will create these messages. Like now, I have Clementine running
but from time to time I will get a glitch and get 2-3 of those messages.
The interval is pretty inconsistent.
