Not sure I can help but if you are hooked up through HDMI, there are protocols that look for the next device in the chain. Your devices or processor may have a setting that turns off the change of devices.

Have implemented the latest firmware upgrade?You should not have this issue IMO
It is like the processor , when changing channels, stop using the former audio format . Then , it is not able to set the new format ( that
may be the same ) . You have to go back and forth for the processor
to set the audio format.
Ask you dealer or communicate directly with McIntosh.
Go to McIntosh MX123 forum
maxwave....Yes, it has the latest firmware. I agree I should not have the issue, but this is the second MX 123 with the issue. I returned the first unit and got another. I assumed the first unit was defective but now I'm thinking it may be a design flaw. I have spoken with both the dealer and with McIntosh directly and both say they have not heard of this issue. I want to keep it because I am pleased with every other aspect of the processor. I will look to join the avs forum and post the concern there.
