[SOLVED] Hardware volume control on Topping D10

[TheOldPresbyope]

@TheOldPresbyope
On your Khadas rig whats the output from cmd below? I think for last release I'd like to slip in an improved routine for parsing out the mixer name :-)

Code:

awk -F"'" '/Simple mixer control/{print "(" $2 ")" ;}' <(amixer -c 0)

Here's that along with full amixer outputs for cards 0 and 1:

Code:

pi@moodeLR:~ $ awk -F"'" '/Simple mixer control/{print "(" $2 ")" ;}' <(amixer -c 0)
(PCM)
pi@moodeLR:~ $ amixer -c 0
Simple mixer control 'PCM',0

 Playback channels: Mono

pi@moodeLR:~ $ amixer -c 1
