I am running xenial64 on a vostro 1320. I run the USB audio output from the laptop to a USB DAC and into my amplifier.
The problem comes when I try to play an MP3 player audiobook to the mic input of the laptop. If I enable mic input in retrovol, it plays through the laptop speakers using the internal sound card but nothing using external DAC sound card.
Is there any way to play the MP3 using DAC sound card.
PS I don't have any spare audio inputs to the amplifier.
Thanks

Delete that .asoundrc file.
I messed around and got the following to work:
1. Card 0 is the internal sound card.
2. A cassette player has its audio output connected to the Mic input of Card 0 with a 3.5mm male-male cable.
3. UNmute the Card 0 Mic input in Alsamixer.
4. Card 2 is a USB sound card adapter.
5. Its output is connected to some headphones
6. From the terminal, run
7. Play a cassette. The audio comes out the headphones.
