Snap.Net >v0.26.0.1 crashes when opening volume mixer

[throny]

I just updated my 0.25 to the latest release. However when opening the volume mixer for the different clients in v0.26.0.1/2 the application crashes without further information. The issue does not occur in v0.26.0.0 I can reproduce it on different windows clients. I guess it's something with the Metadata API.

We're running the docker image mazzolino/librespot-snapserver if that might be a reason but I couldn't find any errors in the logfile.

I can provide you with logs if you want :) (and if you tell me where I could find them)

Hi! I am having trouble reproducing this, so logs would definitely help :) You can follow these instructions to get them.

Thanks!

Edit: what version of snapserver are you running? The Snap.Net versioning always follows the snapserver releases, so if you're using snapserver v0.25 you should also stick with Snap.Net 0.25.x until your snapserver has been upgraded

Edit 2: This is almost definitely the cause of that crash you're seeing - that docker image you mentioned was last updated 6 months ago, and snapcast 0.26.0 was only released last month. Please send me those crash logs anyway, it still needs fixing from my end :)

Hi, I almost thought so, that's why I brought up the Docker image. Thanks anyway for taking the time. :)

This is the error log:
