Using screen as a "window manager" in the Linux console of my Thinkpad,
I've bound certain keys to adjust volume up and down using amixer.
In my ~/.screenrc there is:
# Decrease & Increase volume
bindkey "\033[25~" exec ! amix-adjust minus
bindkey "\033[26~" exec ! amix-adjust plus
Where "amix-adjust" is a script:
#!/bin/sh
# for adjusting the Master volume level (used with Gnu Screen)
amixer -q set PCM 74%
if [ "$1" = "minus" ]
then
amixer -q set Master 1dB-
screen -X backtick 7 0 60 amix-level
elif [ "$1" = "plus" ]
then
amixer -q set Master 1dB+
screen -X backtick 7 0 60 amix-level
else
exit 0
fi
And amix-level is another script:
#!/bin/sh
# for displaying the Master volum level set via amixer (used with Gnu Screen)
amixer -c 0 get Master | grep -m1 -o [0-9]*%
This works fairly well, displaying the volume level "realtime" as
a percentage in the caption line. One quirk though -- when holding
down the assigned "plus" or "minus" key, after enough sequential
repetitions a message will flash in the message line:
Filter running: !.. amix-adjust minus
This is with the keyboard repeat rate set to 30 characters per second.
Reducing the repeat rate to 22 makes the message goes away...but I'd
like to leave it set to 30. Is there some other way to silence that
output?
Thanks,
John
