I would assume that this has been an issue here before but have not found anything that may help.

I bought a new TV last week. My AVR is a Yamaha RXV1400. It is about 6 years old and does not support HDMI. I was initially thinking a new AVR, but with help from this forum and seeing the prices to replace my AVR, I decided to bypass it and connect my cable box and Blu Ray directly to the TV via HDMI and run digital lines for audio to my receiver. (My receiver supports 5.1 analog, but not my cable box nor my Blu Ray, so this is currently my best audio option)

Of course one known drawback for this is when I switch between sources, I have to swith the AVR for audio and the TV for video. I am OK with this though for now.

Here is the problem that I have come across; When I swith from HDMI-1(cable) on the TV to HDMI-2(Blu Ray) to watch BluRay, the player recognizes there is an audio out and sends audio correctly to the AVR. BUT, when I switch back to HDMI-1 for cable viewing, the cable box attepts to use the HDMI for the audio signal. I have to go into cable box settings to correct the problem. Turning cable box on/off has no change, but between sources, I have to reset the cable box audio each time.

My question is, is there a way/shortcut/trick to avoid this? My cable box is a couple years old, I think, maybe a newer box would be more up to date to handle such a dilemma? (I have Time Warner)

Any suggestions?

Thanks for all help!

Many TVs supports an optical audio out which contains the audio from the HDMI feed. If yours do, you could use that.

My TV does indeed have a digital audio out. This would take all audio from the source via HDMI to the TV, then to the receiver? I then wouldn't have to switch audio at all?!?

Test it with copy protected material (the sources with which I tried it -- and use it -- do not have copy protection).

I am currently trying out. I seem to be having difficulty. I suppose it is what you say about copy protected material. (currently Lord of the Rings in) It will not send the digital signal to the receiver because of this?

This makes me wonder why the digital out then?

Verify if you need to setup something in your TV's menu.
And try with a regular CD.

hmmm, unsure if I am missing something or not. I am getting a audio signal, though I cannot seem to get a digital audio signal.

I have checked TV settings and setup, seems to be nothing about confirming a digital out.

I have tried cable channels (confirmed HD content), DVDs and CD's. All the same results.

I can only assume the digital audio out is there when using component video or other video in, but not HDMI for whatever reason...

Like I said, the Blu Ray player seems to know what to do, the cable box does not. Maybe try a new cable box?

I appreciate your help EFalardeau. Any other ideas?

In your source (cable box, DVD player...) are you using "bitstream" or "Linear PCM" for HDMI audio out?

Blu Ray is bitstream. Cable box, I can find no info.
