We were not disabling the audio amp when we changed filer modes.

I've now updated this in my local repo and I will release a new test version later (to latest.sgl)

We are probably not disabling the speaker when changing TS. I will check this and change this if necessary

OK.

I checked. We are disabling the audio amp when we change TS, but we are not resetting the DMR system, because we constantly receive on both TS and filter when which TS to extract the audio

However, I tested changing the TS where one TS is active and the other is not, and I do not hear any hiss on the inactive TS, even though I changed to it many times.

Does this problem only exist when TS filtering is disabled? But I can't see how to test this, because my radio immediately changes back the TS with the signal if TS filtering is disabled
