I have a working librespot/moodeaudio config using --Device <hardware>, however I want to try two zones so I can vary volume from my terminal.

The following ~/.asoundrc allows me to successfully play a wav with "aplay -D quad2 <wav>" to my new PCM "quad2" which duplicates my audio out to 2 USB headphone audio cards:

Code:
pcm.quad {

    type multi

    slaves.a.pcm "hw:0,0"

    slaves.a.channels 2

    slaves.b.pcm "hw:2,0"

    slaves.b.channels 2

    bindings.0.slave a

    bindings.0.channel 0

    bindings.1.slave a

    bindings.1.channel 1

    bindings.2.slave b

    bindings.2.channel 0

    bindings.3.slave b

    bindings.3.channel 1

}

pcm.quad2 {

    type plug

    slave.pcm "quad"

    ttable.0.0 1

    ttable.1.1 1

    ttable.0.2 1

    ttable.1.3 1

}

However when I change my librespot config to --device quad2 (instead of <hardware>), I get the following errors:

Code:
librespot[432]: ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM quad2

librespot[432]: [2019-07-06T14:42:24Z ERROR librespot_playback::player] Could not start audio: Alsa error: PCM open failed  

Google has decided that I am in the Wild West and am on my own, so I appreciate any feedback and suggestions!

What version of Raspbian?

v9 (stretch) on 4.19.42-v7+ and MoOde v5.3.1. Hardware is a Pi 3+

moOde places its own ALSA virtual device files in the following directory:

Stretch

Code:
/usr/share/alsa/alsa.conf.d

Buster

Code:
/etc/alsa/conf.d

You might want to try migrating from ~/.asoundrc to /usr/share/alsa/alsa.conf.d directory

Definitely was unaware that MoOde had it's own device files. I've copied ~/.asoundrc to /usr/share/alsa/alsa.conf.d/ and after a reboot, I have the same error.

I've also noticed that the quad2 is not in AlsaMixer with either .asoundrc scenario and am currently trying to see if that's the issue.

The file extensions are all .conf in this directory.

Code:
pi@rp2:~ $ ls -l /usr/share/alsa/alsa.conf.d

Brilliant little README at the bottom. Renaming .asoundrc to asoundrc.conf was the fix.

Every other song is garbled, guessing a bitrate issue. Super happy tho! Thx!
