I've sent one proposal which uses a notifier to inform audio and CEC drivers about state changes in the HDMI video side, and had precisely zero replies to it - people seemed to prefer discussing stuff rather than reviewing code and coming up with actual solutions.
Do you mind sending me a pointer to this series, I would like to read this up
It isn't a series. It's a prototype patch that I posted in one of the previous threads earlier this month:
Date: Tue, 6 Oct 2015 19:51:57 +0100 Subject: Re: [alsa-devel] [PATCH RFC V2 0/5] another generic audio hdmi codec proposal Message-ID: 20151006185157.GT21513@n2100.arm.linux.org.uk
As I've said there, audio is not the only issue here, CEC also needs to have access to much the same information that audio needs.
CEC needs to know two things: when the HDMI sink is disconnected, and when the HDMI sink's EDID is available (specifically, CEC needs to know the HDMI physical address for itself, which is passed as a number via the EDID HDMI vendor block.)
Right but can I ask why you didn't try making video as component and then CEC, audio and others receive the notification over this. I don't know if there are any limitations to this since you wrote component bits you are the best person to comment...
