!!ALSA configuration files
!!------------------------

!!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.

    this does not seem right:

    
    ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM raspberrypi
    [025b3280] alsa audio output error: cannot open ALSA device "raspberrypi": No such file or directory
    [025b3280] core audio output error: Audio output failed
    [025b3280] core audio output error: The audio device "raspberrypi" could not be used:
    No such file or directory.
    

    Did that reference to raspberrypi get set in the config.yaml in the wrong place somehow? whats in the audio output section for output: and output_device:

    This is what my config.yaml looks like. I followed the setup instructions like every other time and this is how it came out. I haven't touched it.

    I tried changing the output_device of config.yaml to default. When raspbian started I heard the Alexa "Hello" but after that it stopped working. Here is some more debugging stuff. If I need to run a different debug routine, let me know.

    Hey! Sorry for this, it's a bug we missed. Set output_device to default and input_device to either plughw:0 or plughw:1 depending on which USB sound input you want to use.

    Now, all the *_device variables accidentally get set to raspberry. Could you please test / confirm if #99 fixes this for you?

    I am not sure what the hot fix in #99 is asking me to do.

    I have the output to default and the input to plughw:0. when I initialize alexapi manually with the debug script running, it works just fine. I am still having issues on boot though. I hear the initial hello and then when i check what is running with the top command alexapi is no longer running. I would provide a debug file but like I said when I run it that way, it works just fine.

    99 sets up the default audio devices correctly in the config.

    Regarding running AlexaPI as service: https://github.com/alexa-pi/AlexaPi/wiki/Audio-setup-&-debugging#pulseaudio

    Ok, I did the debugging stuff with Pulse Audio and got that running. Alexa worked great. However if I open up chromium and go to youtube and try and watch a video it locks up the system. The video plays but the keyboard doesn't work any longer and there is no audio. Also, if I open up promoe instead of chromium and try and play music, all I get is static. I'm sure this has something to do with me trying to get this crazy stereo to 5.1 upmix stuff working. I have pretty much given up hope of being able to have the 5.1 upmix and alexa at the same time. While it would be cool to have Alexa in my truck on the go, it isn't necessary. If you have any thoughts on how I can get all of it working together that would be great, if not, I will be moving on and I appreciate all of the help everyone has given me thus far.

    -Cam-Op I'm not sure what the issue is - whether it's a PA bug, wrong config, or something else.

    Just to make sure, please post again the output of journalctl -u AlexaPi.service and output when you run it interactively in debug mode, both with the fixed config.
