Operating System HTPC + HDMI + Win7 and its many issues... (4 Viewers)

[gibman]

2 problems afaik.

1) audio device lost/re-found. Ive seen MP even crash because of this.
It should be fixable. A simple way of testing this would be to disable the HDMI audio device in control panels=>sounds.
it should cause the same symptoms.

2) multiple resolution changes
According to our internal private thread our dev 'SilentException' verified that none of the attached event listeners receive any notifications about resolution changes.
So it seems they are hard to act upon
Also each of the resolution events are very costly - and you have 2 of these, 1 for the initial 1024x768 res. and another one for the HDTV res.
try and hit alt-enter and measure the time it takes for MP to change to windowed mode and back.
so even if we get this thing working it's likely to perform in an optimal way.

Hi and thanks for your answer.

Regarding 2), on my system I'm 100% sure that the onSizeChanged event was triggered when turning TV off/on. When setting secondary adapter resolution to same as primary (HDMI) adapter the event was not received due to the fact that the resolution are the same thus no change. I can also recall that MP ended up in windowed mode after this, confirmed in logs and also noticed it due to the fact that GUI calibration was lost (different calibration files for fullscreen resp. windowed mode).

I'm quite sure that I've posted logs about this somewhere... I will try to find them.

Found the logs https://forum.team-mediaportal.com/...tialize-sound-device.90300/page-3#post-774637

Actually related to the BASS init problem, but it's easy to see what's happening with the multiple resolution changes when turning TV on/off as well. Just search for "Main: OnSizeChanged" in MediaPortal.log.

Why are the resolution changes so expensive, e.g. XBMC does this instantly.

I just tried the devcon rescan trick on the problematic nvidia gt220 setup - sadly it has no effect.
black screen, input detects no HDMI signal.

back to the drawing board on this one.
atleast it works like a charm on ATI setups.

the issue I reported in the initial post regarding nvidia setup coming out of standby with no video at all.
well.. this just happened on the ATI setup as well.
atleast its consistent.

luckily I found a solid way to overcome this and I suspect the nvidia setup will benefit from this as well. will report later

Hi Gibman,

I just installed CCC 12.8. It seems ATI solved the loss of audio through HDMI issue. I can switch my bravia D3000 or/and my yamaha 661 off and on as much as I want. Music keeps on playing.

In addition, I can also PLAY A MOVIE and switch things off and on as I like. It keeps on playing after (after I did the VNC monitor resolution trick) .
Only thing Im facing atm is weird fps detection (fixed at 24fps...)

Just to let you know and hoping you have similiar experiences.

 

[gibman]

thx for the notification.
Im already running the new drivers.
so far so good.
btw. I have still have the tape attached to the hdmi pin.
maybe I should try without it

I must say I haven't had any trouble with my setup, worked right out of the box. HDMI on motherboard. I feel sorry for you guys I know how bad it can get. if you want any specs let me know.

Its almost to good to be true....

• SolidWorks: Graphical corruption is no longer experienced
• Crysis Warhead: No longer crashes when launched in DirectX 10 mode
• System no longer hangs when resuming from sleep mode

.... it was too good to be true for me I updated to CCC 12.8 today and ended up with no audio (my Marantz amp doesn't even register that there is an audio input) PLUS adjusting the colour/brightness/contrast settings etc had no effect at all (screen was way too dark) Rolling back to CCC version 10 or whatever I had installed previously while I type thanks to Acronis True image.
