Help sending arguments to Snapclient in Snapos OpenWrt

[JuliusMe]

Hello.
I have two clients in two OpenWrt routers. With default settings both of them have continuous audio dropouts.
If I send any argument to Snapclient command It returns an error: Exception: No audio player support

root@JukeWrt:~# snapclient -v
snapclient v0.20.0

root@JukeWrt:~# snapclient --player alsa:buffer_time=100,fragments=4

It seems that any argument in the config file are ignored, It can not be seen in the log.
SNAPCLIENT_OPTS="--player alsa:buffer_time=120,fragments=4"

Am I doing something wrong in sending the arguments to the player?

[JuliusMe]

I changed snapos makefile to v0.25.0 and recompile.
Now the exception does not appear and the command snapclient --player alsa:? and other arguments throw no error.
So the issue appears to be solved updating to a recent version.

Anyway I have continuous audio dropouts. I have try several server and client buffer values without success.
