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