audio related problem

1. pactl error in crontab script

**** XDG_RUNTIME_DIR=/run/user/$(id -u) /path/to/script

pactl 是用來 heartBeat bluetooth speaker 的, 因為15min不用會入睡, 既不想站起來按一下, 也不想設為永遠不入睡, 只好寫了個 heartBeat scrip, 每10min就 pactl set 一下

...原以為因為是這樣才不入睡的, 結果過去幾天都fail還是沒入睡?

2. headphone volume control fail

in /etc/pulse/default.pa 

  load-module module-udev-detect ignore_dB=1 -> for MM-1 volume control problem

but this option make headphone volume control fail

2023/07/24 update, alsamix -> headphone volume increase to normal

load-module module-alsa-sink control=PCM

3. microphone

/etc/pulse/default.pa set-source-volume 1 300000

/etc/pulse/daemon.conf avoid-resampling = yes

4. restart pulseaudio

pulseaudio -k
pulseaudio --start
