Yes, but only on my AMD Phenom, and I think I've seen it across all
releases from the past few years. 'killall -KILL pulseaudio'.
At one time I removed all its config files and let it regenerate
them when next used, but the issue remains.
I've stopped using pulseaudio. ALSA seems to be able to meet all of my
needs. I also noticed the LXDE desktop constantly maxing out one of
cores (Intel), so I just use xfce.
I think I may do that on my workstation at my next personal build. I'll
need it on my development system though for the book. I went through
blfs and pulse is optional in every case. The description we have is:
"It allows you to do advanced operations on your sound data as it passes
between your application and your hardware. Things like transferring the
audio to a different machine, changing the sample format or channel
count and mixing several sounds into one are easily achieved using a
sound server."
For a single user with output to a single speaker, it seems to be bloat.
Does anyone here actually use any of the advanced features that pulse
is designed to provide?
The closest we have to a required package is FF where Ken wrote in the
optional dependencies:
"PulseAudio-12.2 (or alsa-lib-1.1.8 if you edit the mozconfig; now
deprecated by mozilla)"
