Tasker profile not changing In-Call volume - frustrated!

Have you tried running the action on its own? This will test that the profile is getting activated. Try it with Volume Control+ both running, and not running.

It could be that Volume Control+ is overriding the Tasker setting. What happens if you kill VolumeControl+ at the start of the Action?

If Tasker won't change the in call volume at all, I'd check with the Tasker discussion group - Pent's normally fairly responsive about this sort of thing. He's always responded to me, anyway.

 

The problem is likely that once you are receiving or making a call, you're no longer in the Custom Car Home app. So Tasker changes the in-call volume to 5 when it sees Custom Car Home as the foreground app, but when a call comes in (or you make a call), Custom Car Home is no longer the foreground app, and Tasker sets the in-call volume back to its previous value.

Although Tasker has a variable that you can use to determine the current speakerphone setting, you can't use this as a context since it's not monitored. You could try triggering based on going off-hook and then conditionally setting the in-call volume:

Context: Phone offhook
Task:
In-call Volume 5 If %SPHONE ~ on
In-call Volume 3 If %SPHONE ~ off

Each time you go off-hook your in-call volume will be set based on the current status of the speakerphone.
