Snapcast client default output device

Help
1

Does someone know how I can define the default output device for a snapcast client on a pi 4?

If I run snapclient -s 4 everything runs fine. Using snapclient without any args results in no sound at all because the default device is used.

My snapclient config file:

START_SNAPCLIENT=true
SNAPCLIENT_OPTS="-s 4 -h"

Using this config results in this output:

Btw does someone know what the cache_exhausted log means?

I’ve got it sorted out by opening an issue on github.

Solution is removing the empty -h flag in the config file:

START_SNAPCLIENT=true
SNAPCLIENT_OPTS="-s 4"

If you run snapclient using the command line the config file isn’t used at all. This is intended by the developers.

So just run sudo systemctl restart snapclient and it should be up and running.
