Shodruky,
I'm having no luck with usb sound on my headset. I modified my .asoundrc to be the above file and I got "Cannot open default device" (or similar). Do I need to do anything else to use it?
I've got a Logitech head set connected to my hub and lsusb (which is now working!) shows it as device 5. I work mainly headless so I'd like to use my usb phones for sound.
Your HDMI version of this file works fine. I've gotten sound from vlc and SMPlayer.
I've tried alsaconf that most sites mention but that is not found. alsa-base is installed and up-to-date.
