Pops & clicks in audio

[Richsl]

Running on Rpi3B, running with and then without pulseaudio installed, I could never completely eliminate small pops and clicks every few seconds. Disabled wifi and bluetooth, same issue. With ALSA only (pulseaudio removed) I was getting ALSA 8545 buffer underrun errors. Increasing the -smp buffer setting didn't help, maybe made if worse at settings above 256.

I then used Jack to route the USB audio from the m8 to my soundcard according to https://github.com/laamaa/m8c/blob/main/AUDIOGUIDE.md and then run rm8 -noaudio In this case the audio runs clean with no pops.

I may have messed something up on my system, I am also having some low voltage issues, but audio is still clean with Jack.

Hi,
The audio feature of rm8 is highly experimental and now I believe it's not really the way to go (i.e: build a software loopback like I did).
With SDL I have no real control on latency and other stuff and I'm not sure running that kind of code in userland is fast enough.
Anyway, I have no time right now to investigate other solutions as I am working on other stuff.
Also, now that I have my M8, I haven't use rm8 in days since I use my M8 directly far from my computer.
