Different Control Points; Different Behaviour

Post by tokenbrit »

I posted this in On the Inside - my HAKAI plays ALAC/m4a files when controlled by BubbleDS, but Kazoo won't add the same files to a playlist. Jewa replied that ALAC plays fine on his HAKAI using Kazoo, so it can work...

Checking mpd documentation, it says all decoders are enabled by default, and that's reflected by running mpd --version on my HAKAI, verifiable for a number of encoding formats via BubbleDS, including ALAC.

So do control points query the renderer to find out what formats can be decoded by the player. If so where is this information in HAKAI (upmpdcli & mpd)? It's not in mpd.conf, but is reported by running mpd --version.

My (limited) understanding is that the control point talks to the renderer (umpmdcli) rather than to the player (mpd) so is there something I should be looking at in upmpdcli for ALAC/m4a to play on my HAKAI, controlled by Kazoo, same as when controlled by BubbleDS?

You already figured it out
1. It’s not mpd or upmpdcli, because you can play alac when using bubbleupnp as control point.
2. If the above is true, then the problem is Kazoo (in combination with upmpdcli).

Jean Freancois Dockes told me the next upmpdcli release will include optimisations for working together with Linn Kazoo controlpoint.

I'd put it down to that too, except it works for Jewa...

I'll have to double check library versions later, otherwise hope that it works after reimaging, or wait for the next upmpdcli

ALAC works for me with Kazoo but I am using the iPhone version and using it with Volumio so I doubt it is relevant to your situation.

Thanks Tom, helps to know that it should work, but all a bit odd...

Have you found solution to this ALAC issue? My Kazoo behaves the same. Just saying adding files to playlist but nothing is added... weird.

To answer myself and hopefully this helps others too;
I changed these two /etc/upmpdcli.conf parameters (one of these might be enough - haven't tested...)
upnpav = 0
checkcontentformat = 0

Now my Kazoo plays ALAC files nicely :)

I just altered the checkcontentformat and ALAC now plays in Kazoo
