[ATI] HDMI Audio disconnected when MP turn monitor OFF (1 Viewer)

[azzuro]

Hello.
i have this issue, maybe related to my hardware :
HTPC (DVI to HDMI adaptater) --- hdmi ----> TV
the DVI hdmi adapter is the official one, wich support Audio.

Step :
- Verify than " Turn off monitor during blanking screen" is checked.
http://wiki.team-mediaportal.com/1_...guration/11_General/5_Startup_Resume_Settings
on Wiki : none explanation on this setting.
- Start MP , play music and don't touch anything
- After few minutes, the TV screen is black with notifciation " no signal" and also none audio is played.
- move remote or keyboard active screen and audio continu to be played

Hi azzuro,

is this a bug report? From what I read you could just have found a bug. Maybe you should ask @HomeY what to do with this if he is able to reproduce.
I doubt it is hardware related. Or do you have a setting in your TV to disable or go to standby after x minutes of no signal?

since when did you stumble upon this phenomenon?
Could be since >MP1.7? There was some work done in the blanking screen settings some time ago.

Could it be related to this?
https://issues.team-mediaportal.com/browse/MP1-2053?jql=text ~ blank ORDER BY updated DESC

try disabling idle timer / screensaver and see if the problem is gone. ?

 

[HomeY]

I can't reproduce.

On my HPTC i have a receiver in between (and a HDMI splitter attached to the receiver output) and when it blanks, it doesn't turn the TV off, nor does the audio stop. Keeps running fine.
On DEV i have 2 monitors connected, 1 directly with HDMI, another with DVI > HDMI dongle. Here the monitor doesn't get turned off either when the screen is blanked.

I don't use the MP screensaver option, simply set Windows screensaver to blank the screen after 1 minute.
Azzuro, Do you have the MP screensaver set up?

 

[azzuro]

Yes. Mp Screensaver is activated. Uncheck the option turn off monitor. Solve the issue.

 

[HomeY]

Yes. Mp Screensaver is activated.

I can reproduce it when i use the build in screensaver, instead of windows screensaver directly (which both should be the same, since build-in uses windows screensaver).
But when i use the build-in screensaver, and UNcheck the option to 'stop playback on removal of an audio renderer', then it works fine. Monitor gets turned off and radio kept playing fine.
I assume you have this option checked?

If so, disable the check, enable 'turn of display' again and re-test should work then.

 

[azzuro]

I assume you have this option checked?

hum " stop playback on audio removal" is set ON
what you ask me to do ?

- disable MP screensaver
- UNcheck "stop audio on removal"
- check on , Turn off monitor inside MP ?

 

[HomeY]

what you ask me to do ?

and UNcheck the option to 'stop playback on removal of an audio renderer',

Leave screensaver on, keep check on 'turn off monitor', disable 'stop audio on removal'. Then try again

 

[azzuro]

Ok. Imust test

Ps: i have an old ati card 4650 with dongle dvi to hdmi. Maybe the issue

 

[HomeY]

i have an old ati card 4650 with dongle dvi to hdmi. Maybe the issue

I've tested this on DEV with onboard HD4000 with HDMI > DVI dongle. So doesn't seem related to the dongle but with the setting 'stop playback on removal of an audio renderer'.
After unchecking that option, everything is fine here, screen is blanked & monitor is turned off. After that, music keeps playing fine.
With the option checked, music stops when the monitor gets turned off.
