I am trying to configure my USB sound card for use on the pi. With the graphical interface, I can change the sound card and output the sound to the USB card.
Without the graphical interface with Putty (no screen in HDMI), the sound does not come out of the USB card.
I modified this in the /usr/share/alsa/alsa.conf
file:
defaults.ctl.card 1
defaults.pcm.card 1
cat /proc/asound/cards
