#1160 Audio Routing for HTC Incredible

[Anonymous]

What steps will reproduce the problem?
1. Make a phone call w/csipsimple on HTC Incredible
2. Other party answers and talks
3. Other party hears "echo" of themselves talking ~2 seconds later

What is the expected output? What do you see instead?
I expect there to be No Echo, instead echo is present and intolerable.

What version of the product are you using? On what operating system?
0.02-03 [r944]

Please provide any additional information below.
After much struggling, I FOUND THE SOLUTION.  For the HTC Incredible, Change "Audio mode for SIP calls" from IN_COMMUNICATION to IN_CALL.  Audio then sounds great, and best of all, NO ECHO!!!

Yes, indeed according to device there is sometimes workarounds like that.

If HTC did a clean implementation of android 2.3 on your device IN_COMMUNICATION should also cancel echo cancellation the same way IN_CALL mode does.
Blame HTC for that ;) .

The problem is that if I set IN_CALL to be the default option for HTC incredible, it will probably break things according to ROM one is using. For example on some ROM it is possible that IN_CALL mode does not allow to record audio at all.

Besides, another point, I think that enabling IN_CALL mode you broke the "rear speaker" feature.
In order to workaround this case, there is a better "workaround" setting in csipsimple : try to use "Use Mode API" instead (when trying to route to earpiece, it will use mode IN_CALL and when routing to rear-speaker it will use mode NORMAL).

Anyway, thanks a lot for sharing the information. It will will be helpful for other users with this device.

I merge with issue 119 to try to not be lost with all issues ;).
issue 119 is the tracking one about echo issues, and there is already other useful hacks for other devices.
