Hi Kyle,
So can I install pipewire in Ubuntu with the following?
sudo apt install pipewire-pulse -y

?
Thanks

I tested Pipewire here. It was very easy to install it, and just
installing pipewire-pulse completely replaced Pulseaudio automatically,
which was very nice indeed. In fact, it even told me that my pulseaudio
and pulseaudio-bluetooth packages were in conflict and allowed me to
remove them. I didn't have any problem with speech-dispatcher not being
interruptable, and a rec/play pipe echo test gave me much lower latency
than Pulse. However, after a while, my USB sound device started
glitching just a bit after recording. It sounded much like a scratched
CD that is not scratched enough to skip, but scratched enough to click
click click rhythmically with varying volume. My bluetooth headphones
were also completely unintelligible with speech-dispatcher running. I
tried playing a song using sox, and the sound came to my headphones
without issue, but then as soon as I started orca and speech-dispatcher,
both the speech and the song I was playing became unintelligible. My
tests with my USB device using Audacity resulted in increasing latency
every time I recorded a new track. It's possible this had much to do
with the clicking I was hearing, but it could have also had a lot to do
with the fact that I was testing a rather involved set of short tracks
on top of a longer track, which introduced more latency each time a new
track was recorded. It seems Pipewire, at least the Pulseaudio
replacement portion, could use a bit of work especially on USB and
bluetooth devices. Otherwise, it's a good start, and is actually better
than many onboard sound chips have been with Pulseaudio, especially in
the beginning when it became the default in Ubuntu back about 12 years ago.
