bluetooth headless deck for car - EL-D01 USB DAC no sound!

[kidkangaroo]

Hi guys - I'm working on getting a EL-D01 USB DAC work. I've built the bluetooth headless pi for streaming audio direct to my amp in my car (see instructables for great tutorial!)

Anwyay - so it plays from the headphone jack just fine, just can't get it to output or work with the DAC.

I think it can see it just fine:

I've updated /etc/modprobe.d/alsa-base.conf with the following: (found on http://drewlustro.com/hi-fi-audio-via-a ... spberry-pi)

Code: Select all

#options snd-usb-audio index=-2
options snd-usb-audio nrpacks=1

and also updated /etc/asound.conf with the following:

Code: Select all

pcm.mmap0 {
    type mmap_emul;
    slave {
      pcm "hw:0,0";
    }
}

pcm.!default front:DAC

But still no love...
