Anyone have this problem?


Hello all.....I just recently purchased a new McIntosh MX 123. Looks and sounds great. I am having an issue though. While watching tv through the processor, when I change channels it drops the audio. I have to switch inputs and then switch back to get the audio back. This cannot be normal, or perhaps McIntosh assumed it would not be used to channel surf. Any experience or comments?

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.

Have you tried switching hdmi cables?  I know it sounds dumb and “digital is digital” but just today was trying everything to get a Nintendo switch console working and finally went from the cheap hdmi cable (which I know does work) to an older but very expensive at the time Monster cable and boom, problem solved. 
esthlos13....I switched HDMI cables, I switched the cable boxes, I tried a different HDMI input, but the problem persisted.
