Update: Switch your listening mode to "PLXII Movie".
Next try turning off the cable box, then the Onkyo, and then the cable box and Onkyo back on. PLIIx Movie can decode better channels and this will prevent the Onkyo circuitry from attempting to match the output on whichever channel you are watching.
Turning off both devices, unplugging the Onkyo, plugging it back in, powering on the Onkyo first and then powering on the Cable Box appears to have corrected this exact problem for me, Scientific Atlanta 8300HD box from Optimum Online (Cablevision), and Onkyo TXSR-805. I also changed one setting under Setup for the Onkyo TXSR-805, here is that setting:
- Setup Screen
- Under 3. Audio Adjust, select option 2. Direct.
- Change 'Delay Enable' DSD from No to Yes. This was a hunch, from the manual text below.
- Also, I am using Stereo listening mode, at the moment with only two front speakers.
This combination is working well. I attribute the improvement to turning on the components in a particular order / rebooting the hardware on both to improve the HDMI handshake.
I had the exact same issue of frequent popping and the audio frequently stopping after the popping, within five or ten minutes of using the cable box and changing channels, particularly ESPN perhaps because of HD audio. The troubleshooting combination listed here appears to have corrected the problem at least for the past several hours. This problem randomly started happening after three or more years of using the exact Scientific Atlanta 8300HD DVR box from Optimum without issue, with the Onkyo TX-SR805.
Quoted from the Manual, curious if there is any input as to why this may or may not help with HDMI audio from a cable box. In my mind, it makes sense that audio signals are processed by the Digital Signal Processor.
This setting determines whether or not DSD (SACD)
audio signals are passed through the DSP for A/V Sync,
delay, etc., processing when the Pure Audio or Direct listening
mode is selected.
DSD signals are not processed by the DSP.
DSD signals are processed by the DSP."
Good luck with your Onkyo 805.
