[PROBLEM] Using GPIO to Pause/Play

[xaszy]

Hello together,

i am testing an rotary encoder with an rpi which works fine so far for volume. It has a lot of bounce, but i did not dig into that for now, will do that.
What i am trying to do is to use the push button of the rotary encoder, to pause / play and not only "mute".

I found that there is a gpio handler with some command options and i did find how to vol up and down and mute via the vol.sh, but i could not figure out how to pause a playback with the button.

Could anyone help me, what need to get in the command field to actually pause a playback ?

Thank you very much,

best regards,
