Occasionally, when I turn on my Cisco CHS 435 multi-room DVR, my favorite channel has no sound.
I live in Baltimore County, MD. The channel in question is 526, the HD feed of the WETA-26 PBS station in Washington, DC.
When this happens, all the other channels' sound is OK. I can't get sound back on 526 by switching to another channel and switching back. I can get sound back with this trick:
- Switch to another channel.
- Begin recording whatever is showing on that channel.
- Switch manually to channel 526.
Now channel 526 has sound. I then can stop and delete the current recording-in-progress.
I believe the trick works because it forces the DVR to switch to the other tuner for 526.
It is posible that the audio drops during or at the end of an earlier recording of channel 526 that I had set the DVR to make, such that when I turn on the DVR later on, 526 is the active channel and it has no audio. That seems to be the pattern, but I haven't really confirmed it.
I am using IMG 1.9. The S/N ratio for the DVR is shown as 23 dB. I have no other known problems with the DVR or the two other Cisco set-top boxes in my home.
I have no reason to believe that the audio problem has to do with the WETA source signal, as the trick I outlined above brings the audio back successfully, and I have never had a problem with 526 on my TiVo units with CableCards.
Does anyone have similar experiences to share ... or maybe even a solution? Thanks.
