I looked everywhere and for quite a while for a solution to my problem but I couldn't find anything so hopefully somebody here can help.
I have the following setup:
- Sharp projector XV-15000
- Sony AV receiver STR-DN1010
- PVR box Scientific Atlanta 8300.
All my devices, including the PS3 and the XBOX are connected to the AV receiver through HDMI input ports and the receiver to the projector through the HDMI out port using a 25ft HDMI cable.
Everything works fine, except that when I watch TV and change from a HD channel to a standard definition channel and vice-versa, I lose the sound. The solution is to either unplug the projector or to change through the remote, from one input to another and back but this is really annoying.
This doesn't happen when I change from an HD channel to an HD channel or from a standard to a standard. Also I didn't have this problem when I used to output the video to a Sharp HDTV. However, before the Sharp projector I had an Epson 8345 and I noticed the same behaviour.
My guess is it's the HDMI cable to blame, although I tried a couple of them with no luck. If it's indeed the cable, which one would be a good one, at a decent price? If it's not the cable, what could be the problem?
Any help on this is really appreciated.
