Apologies for the new post- I know that this subject has been discussed in a previous topic, but I could not find it when searching. I have an HR24 connected to a Denon Receiver via HDMI. I have been having the following issue- losing audio on some SD channels when switching back on forth on tuners. It took me awhile but I have pinpointed the problem and can now duplicate it anytime. I have found that if I am watching TV LAND on tuner 1 and am NOT live (I have paused the live tv), THEN switch to tuner 2. When I switch back to tuner 1 to watch TV LAND (channel 304)- if I am not live, the audio is gone- it happens every single time. This also happens on QVC (channel 275/317)- I am not sure if it just these two channels or if it is any SD channel/program- so far this has not ever happened to me with an HD program. There is no way to get the audio back except to change the channel, clearing the buffer, then changing back to it. (I’ve tried everything- turning the receiver off, the tv, etc, etc) It also does not happen if you are live on TV land or QVC- if you are live, you can switch back and forth between tuners with no loss of audio. Anyone know what is going on here?? I know it is not just me, because somewhere on this forum, others were having the same problem (I just can’t find those posts)….
