Hi all,
I own a RPi B+, I wanted to attach use the usb sound card as default but I didn’t manage at all. I googled for about 2 days… but no help.
The max I could made is to use aplay or speaker-test using -c 2 with D hw1 (or plughw1). But no more .
Please help!
I attached all my outputs from the commands I made till now:
modprobe.d/alsa-base.conf" is :
options snd_bcm2835 index=0
options snd_usb_audio index=1
options snd=snd_usb_audio,snd_bcm2835
If I put 0 to usb the usb don’t appear at all.
aplay -l:

I ran the script from alsa-project.org, the link is: http://www.alsa-project.org/db/?f=c58b2369558ac131fe87ed2aab0cf27f4ed43fb3
And to be true after hundreds of changes, the system is not working at all right now
Help .
