Subdevice #0: subdevice #0card 2 is the 5.1/7.1 usb sound card that I have plugged in. I can only hear music from my iphone using shairport and alexa responses on the stereo channels. If I plug the speakers into any of the other ports (rear, center/bass, sides), I don't get anything at all. However as already stated if I play an mp3 with promoe or vlc I can change my speakers to the different outputs and still hear a left and a right channel. I can also open up chromium and stream something and do the same thing. I can also say that the only audio I now get comes from the usb sound card as it is set as my default card. If I plug the speakers into the pi at the 3.5mm output, I hear nothing at all. I can't test the HDMI right now as this monitor doesn't allow for sound but as long as the default is set to the USB sound card that is the only thing that should be working.

7 years ago I should also add that I edited line 29 of the asoundrc file to say card 2 instead of card 0.

7 years ago try the aplay -L with a capital L, that should give you the list of devices with their hardware names (i.e. plughw:1
One of those should represent the upmix, and then you should be able to just set that as the output in config.yaml

commented
7 years ago ok so stupid question will get the obvious answer probably. Where is the config file located? I checked the /opt folder and couldn't find it. I also did a file search for it and the only config.yaml that comes up is completely empty. I know the Alexa service wouldn't be working if there wasn't a working config file. also here is the output with -L.

7 years ago ok, cool - first the file is in /etc/opt/AlexaPi/config.yaml. and there is a good audio device debugging section in the wiki here: https://github.com/alexa-pi/AlexaPi/wiki/Audio-setup-&-debugging
Second, set the output device in the config to "surround51:CARD=Device_1,DEV=0"

7 years ago if that doesn't work you may be able to use "ch51dup" - i passed right over that the first time

7 years ago Sadly none of the option I have tried have worked and for some reason, I can't get the sound outputting from the other channels at all anymore. I have no idea how the config.yaml would have screwed with that. it doesn't even make sense to me.

commented
7 years ago do you have pulseaudio running? if so, you may need to run it as a service in system-wide mode and set the config to pulse (rather than alsa). see the section in the wiki for pulseaudio on the pi. the config.yaml is purely for AlexaPi sound input/output so it shouldn't stop audio otherwise, there's likely another problem there too.

7 years ago I see that your original question is about shairplay-sync. That is unrelated to AlexaPi. You might be able to add something to /etc/shairport-sync.conf, but my recommendation would be to ask at the source, here.
AZ-Cam-Op
commented
7 years ago I will do that. Still trying to get Alexa to work on all the speaker channels. I reverted back to a saved disk image I had before I made a bunch of changes. Haven't had a chance to test it yet.

commented
7 years ago Ok so now I think this is relevant. I got the PI3 back up and running. I have disabled the onboard sound card and only have my usb sound card. The usb sound card works just fine with promoe and vlc and creates the 5.1upmix. The alexapi service isn't liking something about the sound card setup and is quitting because it can't play any sound. Below are the three different ways of seeing the debugging info. Perhaps you can point me in the right direction.

!!User specific config file (~/.asoundrc)
# 2008-11-15
#
# This .asoundrc will allow the following:
#
# - upmix stereo files to 5.1 speakers.
# - playback real 5.1 sounds, on 5.1 speakers,
# - allow the playback of both stere(oupmixed) and surround(5.1) sources at the same time.
# - use the 6th and 7th channel (side speakers) as a separate soundcard, i.e. for headphones
# (This is called the "alternate" output throughout the file, device names prefixed with 'a')
# - play mono sources in stereo (like skype & ekiga) on the alterate output
#
# Make sure you have "8 Channels" and NOT "6 Channels" selected in alsamixer!
#
# Please try the following commands, to make sure everything is working as it should.
#
# To test stereo upmix : speaker-test -c2 -Ddefault -twav
# To test surround(5.1): speaker-test -c6 -Dplug:dmix6 -twav
# To test alternative output: speaker-test -c2 -Daduplex -twav
# To test mono upmix: speaker-test -c1 -Dmonoduplex -twav
#
#
# It may not work out of the box for all cards. If it doesnt work for you, read the comments throughout the file.

I am running your program on a raspberry pi 3 with the most up to date version of raspbian. I have found a way to upmix stereo files to 5.1 sound with some setting in the asoundrc file. It works great if I am playing an mp3 with promoe. Is there a way to get it working with shairport-sync?
The following link will take you to the asoundrc file settings.
https://de.mcbf.net/david/dotasoundrc/
please let me know if this is something that could be made possible. thanks.
