ALSAAudioError on Runeaudio

[ThomasBorghs]

I get following error using the latest package released version: 0.0.3-alpha on runeaudio 0.3-beta. I'm trying to output to a USB dac (details below). As you can see in the command I tried passing as much parameters as possible, it keeps giving the same error with any other combination of these parameters, including when I don't pass any parameters other than bitrate and name.

The chroot version works perfectly with the DAC as well, but I want to run multiple instances, 1 for my account, 1 for my gf's (which worked on osmc when I tried it). I tried fiddling around with the naming of "default" parameter assignments, but wasn't able to figure out where the value came from or which call causes the error (my Python knowledge is quite lacking). I would think the problem is linked to the arch linux distribution lacking some package perhaps? alsamixer and amixer commands are available though, so I wasn't sure if anything else was needed.

Any help would be appreciated!

Hi - I couldn't get the 0.0.3 Alpha to work on Rune Audio either. Think you're right that there's some kind of issue relating to Arch. To get 0.0.3 to run, I had to install the following packages from AUR

python2-flask-bootstrap.tar.gz python2-flask-cors.tar.gz python-dominate.tar.gz python-pyalsaaudio.tar.gz (note you'll need to edit the arch version in the PKGBUILD file to 'any' to get this to build on the PI) python-visitor.tar.gz spotify-connect-web.tar.gz

That did the trick, and now I have the 0.0.3 Alpha working great on my Rune Audio.

Would be much simpler for everyone if the chroot was updated to the newest code version though!

Hope that helps.

Hi,

python-pyalsaaudio.tar.gz (note you'll need to edit the arch version in the PKGBUILD file to 'any' to get this to build on the PI)

according to the maintainer of the package you just need to build it using --ignorearch.

@bjo: This builds a C extension, so 'any' architecture is wrong. I have read somewhere that arm users build using makepkg --ignorearch (or -A), is that not true anymore? If so, I can add the additional ones.

It worked for me.

Also, I had the same error you described (https://gitter.im/sashahilton00/spotify-connect-resources?at=5793cd65959ee82b3e47a144) on my Pi2 running Arch. As @TheMattyBoy said already, it can be worked around installing the package from AUR.

The sh: symbol lookup error should be harmless, but the error involving alsa.mixers()[0] is probably a hardware problem. I'm gonna work on adding a better error message for that

Same here... ./spotify-connect-web.sh --username XXXX --password XXXX --bitrate 320 -o sysdefault:CARD=Device -m PCM

results in

I'm using a USB Soundcard on a Raspberry Pi 3, which is working fine with e.g. mplayer. Not sure if that might cause the problem...

aplay -L

@fosple for the -m option, check the output of amixer instead to get the proper device name
