May as well join the fun. Believed I tried every suggested work around
above, still got crackling.
In my case the crackling is present on the line-in 3.5mm jack plug and
not a microphone.
I run:
X470 GAMING PRO (MS-7B79) motherboard with a ALC892, Ryzen 2700, Radeon
RX Vega 54. Running Ubuntu 19.04, Kernel 5.0.0-20-generic (was hoping
kernel 5 would improve things).
I did notice that the crackling reduced a bit when using this setting in
/etc/default.pa
### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect use_ucm=0 tsched=0
.else
### Use the static hardware detection module (for systems that lack udev suppor$
load-module module-detect tsched=0
.endif
I use a Loopback (# pactl load-module module-loopback latency_msec=1) to pipe
some line in audio (chiptune device('s)) into PulseAudio if that's something
useful to know.
Really annoying problem, makes me feel ashamed using Linux, really nice
up to date computer (hardware) and some trivial piece of sillycon
working with every other OS refuses to work on Linux. Don't know who to
blame, but blaming I do!
USB soundcapture isn't really the thing I'm looking for. Unnecessary
latency is often a thing I try to avoid.
Who wants to trade a X470 GAMING PRO for a X470 board that has working
sound on Linux??
