Hi Mauro,
I hope you can fast-track this to Linus! It's a nasty regression. From the log:
"The switch to the new control framework caused a regression where the audio was
no longer unmuted after the carrier scan finished.
The original code attempted to set the volume control to its current value in
order to have the set-volume control code to be called that handles the volume
and muting. However, the framework will not call that code unless the new volume
value is different from the old.
Instead we now call msp_s_ctrl directly.
It is a bit of a hack: we really need a v4l2_ctrl_refresh_ctrl function for this
(or something along those lines).
Thanks to Andy Walls for bisecting this and to Shane Shrybman for reporting it!"
I've tested this with my PVR-350 and the audio is now working properly again.
The solution I've chosen is correct, but a bit too low-level. For 2.6.37 I hope
I can add some support for this to the control framework itself. It's too late
to do that for 2.6.36 though.
Regards,
Hans
