This is the same issue we've experienced in bug 917193 and bug 988760; we've deployed a workaround for the busy tone in bug 988760 which *might* fix this issue too; I'll give it a try and see if it fixes this. However the real issue is bug 848954 so I'm marking that as blocking.

The patch for bug 1022554 has a wrong commit log that points to this bug, sorry about this, and sorry that I didn't check before merging :-(

This patch extends the existing workaround for glitchy short key-tones to the long ones. The day bug 848954 gets fixed and we can get rid of this stuff I'll be a happy coder. Like, real happy.

Can you try out this PR and see if it fixes the problem for you? It does for me on Flame and Hamachi devices.

Comment on attachment 8456128 [details] [diff] [review] [PATCH] Workaround for glitchy long-press key tones Review of attachment 8456128 [details] [diff] [review]: ----------------------------------------------------------------- Sounds good. Literally.

Try was mostly green except for an unrelated integration test that I've seen failing more than once, I've re-triggered it but maybe it's time to mark it as an intermittent issue or something. Anyway pushed to gaia/master 8c702cb54f73683e9681508a8eff2d3ac9bb9109 https://github.com/mozilla-b2g/gaia/commit/8c702cb54f73683e9681508a8eff2d3ac9bb9109
