octo soundcard not working

[nachtaktiv]

hey there

sorry, i'm a complete noob regarding linux and raspberry. first i connected the soundcard with, then without preamp device in between, because i want to connect synths with line signal and i do not need a preamp.

i installed the card (the easy way) and everything seems OK in the terminal, in the raspbian settings the card occures and i thought it would be ready to play. i wanted to test it with a connected soundsource in pure data, didn't work. then i only wanted to hear something by playing a youtube-video in the browser, no signal from any of the outputs.

do i have to do further cofigurations? how can i test it?


cheers and thank you

try:

Code: Select all

speaker-test -c 8

perhaps you have the same issue like me - ch1 and ch2 not working ?

Yes, as bartl mentions, you can use speaker-test.
You can also play wav files using aplay. You can also install audacity :

Code: Select all

sudo apt install audacity

Audacity provides a gui for a waveform editor which allows you to playback.

Please let us know how you are going.
