I made ALSA applications output audio to jack by applying instructions on https://alsa.opensrc.org/Jack_and_Loopback_device_as_Alsa-to-Jack_bridge # Gentoo Linux aarch64 on Raspberry Pi 3 B+ jackd -P 90 -d alsa -d speakers -p 512 -n 3 -P -r 48000 jack_netsource -H 192.168.30.2 -o 0 -i 2 -O 0 -I 0 -n 3 -N guardian # Gentoo Linux amd64 on my desktop computer jackd -P 90 -d netone -p 512 -n 3 -r 48000 alsa_out -j headphones -d headphones -c 2 -p 512 -n 3 -q 3 alsa_in -j cloop -d cloop -c 2 -p 1024 -n 2 -q 3 jackd, jack_netsource, alsa_in, and alsa_out belong to audio cgroup which allocates 95% of CPU time to its group members. While youtube videos are played in vivaldi web browser, chrome web browser, and firefox web browser, I occasionally hear audible pops. It seems all pops come from `alsa_in`. I also tried alsa_in -p 1024 -n 3 -q 2|3|4, but it doesn't eliminate pops. Here's a part of ~/.asoundrc on my desktop computer. pcm.loophw00 { type hw card Loopback device 0 subdevice 0 format S16_LE rate 48000 channels 2 } pcm.lmix { type dmix ipc_key 219347 slave { pcm "loophw00" period_time 0 period_size 512 periods 4 format S16_LE rate 48000 channels 2 } bindings { 0 0 1 1 } } pcm.cloop { type hw card Loopback device 1 subdevice 0 format S16_LE rate 48000 channels 2 } pcm.!default { type plug slave { pcm "lmix" format S16_LE channels 2 rate 48000 } rate_converter "samplerate_best" } Is it impossible to eliminate pops from alsa_in running on cloop which is just alsa loopback?
