Audio loss when switching tv channels from sd to hd channels

Equipment used
HTPC connected to tx-nr515ae via HDMI
A/V Main connected to Samsung 55 Inch series 7 Led LCD TV via HDMI
Using Silicondust dual tuner box connected via ethernet
Using Win 7 MCE to select tv channels. Channels are free to air digital

If I start with standard def channels Audio ok. When changing to High def Channels the audio is not present and if left long enough will cause an error message to be displayed,
from the pc stating file is corrupt etc ( don't understand this! ) and to restart MCE or reboot the pc. Audio is also lost from sd channels. Restarting MCE usually regains audio on sd only.
The problem exists for recorded channels in HD.

Borrowed a set top box for tv. Seemed to work ok. no problems. by this stage had done a clear on reciever and bypassed any setup configurations.
Tried a second computer, setup similar to HTPC. Seemed to be behaving switching between SD and HD channels replaying recorded channels ok etc.
Was about to reinstall win 7 etc on the HTPC, but decided to run the audio balance test, still using the second pc, with the microphone as first done in setup. After completeing this process the problem
has returned to the second computer.
The only way around the problem so far is to do a clear or sometimes selecting the hd channel and quickly tuning off the A/V reciever then on again.

the fimware has been updated to the latest version.

Any ideas?

Thanks Leemus

ps previously using a yamaha A/V reciever untill it died hence having purchased the Onkyo

Thanks for your interest, but in the words of Maxwell Smart, the old remove the plug for 5 minutes trick, solved the problem.
