@Fornoth What's blocking the upgrade to pyalsaaudio 0.8+? I can upgrade on my Pi3 with no problems. Is there particular hardware that it doesn't currently work on?

[Fornoth]

@celeryclub pyalsaaudio 0.8+ itself works fine, the note is more to upgrade to the newer device/mixer selection features in it

[dialupdev]

@Fornoth Understood. Thanks.

Handle when a device doesn't have a mixer

I guess this is the reason why my HifiBerry DAC+ light won't play along with Spotify Connect Web. Is this something that's very hard to fix? If not, can you point me in the right direction, so I can see if I can figure it out?

I use the following for my HifiBerry DAC+ on libreELEC:
playback device: default:CARD=sndrpihifiberry
mixer: Digital

@awiouy
Is that the light version? The other two have mixers, but the light version lacks one.

@makruiten For me the DAC+ Light works, I have got no volume control tho. I'm using the latest runeaudio for the raspberry pi 3.
The lack of a hardware mixer is the reason why we need to use the software mixer.

@ClemaX It was probably due to the way it is packaged in Kodi. I had no problems getting it to work in Volumio. In Kodi you are forced to select a mixer, while there are none. Or at least I was unable to get it up and running.

@makruiten Have you tried adding a software mixer to the alsa asound.conf config file?
