[solved] User Interface HDMI audio to AVR not working or cut (1 Viewer)

[Stéphane Lenclud]

I thought that the availability of GUI sounds depends on your audio output devices?

With my previous TV, I used analogue audio output from the HTPC to an analogue audio amplifier, and GUI sound effects worked fine.

With the TV that I purchased earlier this year, I use HDMI digital audio from the HTPC to the TV, and then analogue audio output from the TV to the audio amplifier. With this arrangement, GUI sound effects do not work properly. Short GUI sounds are completely missing, while long GUI sounds (this is with the Amped skin) are mostly truncated (I hear just the last few milliseconds).

Reading the MP fora suggested that this is caused by one the digital processors in the signal path (HTPC, TV, or digital amplifier) switching itself off when there is no signal, and taking some number of milliseconds to restart when the next signal arrives. So the first few milliseconds of each GUI sound effect are missing. Since you have not posted details of your HTPC system, it is difficult to know whether this is applicable to you.

I decided to disable GUI sound effects.

Did you try http://www.marcsapps.co.uk AVR Audio Guard for your HDMI sound issue?

I did not find a solution when I scanned the fora about this problem (this was several months ago), so I put this issue on the "back burner" for attention at some future time.

Thank you very much for suggesting this solution; I have made a note of it, and will look into it next year to see if it will work with my setup.

I have no navigation sounds. So pressing up, down, left, right, enter etc. makes no sound anymore. I do have sound when playing music, movies etc

Omg....
Did a complete fresh install of windows 10 home. Installed drivers and MediaPortal. No GUI sounds......

Hi, you mentioned that you wanted to open another thread for this problem.

It is not generic since all my systems run on Win 10 and I do have GUI sounds. But I suggest that we take a closer look into this elsewhere.

This is the solution!!!! Thank you

Only curious why windows 7 didn't have this issue[DOUBLEPOST=1450548984][/DOUBLEPOST]

No need for a new thread anymore, problem is solved

Glad that solved your problem.
Different driver architecture I guess. Windows 8/10 have had a lot of improvements to save power and battery life. Stopping sound output when nothing is played is part of that I guess.
Though the audio driver itself could be to blame as well cause I was having that same issue on Windows 7.
I'm going to move those posts to a support thread.

@CypherMK was having trouble with HDMI audio being cut or inexistent when navigating the MediaPortal user interface.

He's issue was solved by using AVR Audio Guard.

I did find another little program which also fixes this issue. It's in this thread: https://community.amd.com/thread/185767

Link to program: https://mega.nz/#!FYR3TKyR!IIuL_eSct-HhXCcX2tymarYR4M2z6Cfg6t-fdSqTzoo

Avr audio guard uses 25% cpu and this program doesn't use any cpu which is better off course.

But I hope AMD or Microsoft come up with a permanent fix.

Shame that guy did not publish his source code:

AVR Audio Guard developer was on MP forum but has not been seen for a while. Maybe we could ask the Sound Switch community to integrate such feature.

The problem really lies with AVR rather than with Windows or driver so I'm afraid it won't ever get fixed.

Most AVR are just not designed for this kind of use case. AVR manufacturers thought it was acceptable to loose the first few seconds when audio input starts.

If this really bothers you, a possible solution might be to try modifying the WAV audio file that MP uses. Perhaps add a little bit of silence at the start? ...or maybe convert it to 5.1 channel so that the AVR does not have to switch modes?

If it works on Windows 7 (in my situation) it should work with every windows version imo.

So it is also a windows/amd/nvidia/intel issue.
