USB audio device - wrong selected Mixer name - eclick - 04-19-2020

Hello, 

can you please help me to solve this problem? I use active speakers with HW knobs (bass, treble, main volume) via USB.


I think there is something broken in configuration - maybe in "Device cfg"?

System select wrong Mixer name = Bass. Maybe because it is first? There should be PCM.

I changed default ALSA volume from 100 to 50 (default?) because of very bassy sound. But it is just temporary solution.


In Volumio i could choose right mixer control, but in Moode is no such settings in UI.


There are few logs from fresh install:

RE: USB audio device - wrong selected Mixer name - Tim Curtis - 04-19-2020

The method for getting the mixer name has changed in upcoming 6.5.0 release.

Try the command below and let me know if it returns the correct mixer name for your audio device.
Code:
amixer -c 1 | awk 'BEGIN{FS="\n"; RS="Simple mixer control"} $0 ~ "pvolume" {print $1}' | awk -F"'" '{print "(" $2 ")";}'

If it works then edit the file below, comment out the existing awk and add the new awk in the specified code block
Code:
sudo nano /var/www/command/util.sh

code block:

# Get alsa mixer name
if [[ $1 = "get-mixername" ]]; then
    CARD_NUM=$(sqlite3 $SQLDB "select value from cfg_system where param='cardnum'")
    #awk -F"'" '/Simple mixer control/{print "(" $2 ")";}' <(amixer -c $CARD_NUM)
    amixer -c $CARD_NUM | awk 'BEGIN{FS="\n"; RS="Simple mixer control"} $0 ~ "pvolume" {print $1}' | awk -F"'" '{print "(" $2 ")";}'
    exit
fi


RE: USB audio device - wrong selected Mixer name - eclick - 04-19-2020

Thank you very much, Tim.

The first command returned PCM. So I modified util.sh and everything works perfectly ... ;-)

The ALSA volume is set back to 100 and the hardware volume is turned on.

Thank you for your work!

RE: USB audio device - wrong selected Mixer name - Tim Curtis - 04-19-2020

This command?

Code:
amixer -c 1 | awk 'BEGIN{FS="\n"; RS="Simple mixer control"} $0 ~ "pvolume" {print $1}' | awk -F"'" '{print "(" $2 ")";}'

Yep.

After edit util.sh and restart:
