SOURCE: Connecting a YAMAHA RX-V2700 receiver to my TV and cable box
why not you use a normal AV cable
instead of hdmi cable
SOURCE: Unable to play DTS-HD & True-HD
What do you hear? Do all other modes work ok?
If Audio Select (Page 44 and 98) is set to HDMI you will hear silence if no HDMI signal is present. I think AUTO is the best choice here.
-------
On Page 98 of the manual it says a bunch of things concerning automatic signal detection and input selection.
Initial configuration D) INIT. CONFIG
Use this feature to select the settings of the audio input jack select, active decoders and extended surround when you tum on this unit.
....

Support audio S. Audio
Use this feature to select whether to play back HDMI audio signals on this unit or on another HDMI component connected to the HDMI OUT jack on the rear panel of this unit.
...

FUNCTION
Plays back HDMI audio signals on this unit. The HDMI audio signals input at the HDMI input jacks of this unit are not output to the HDMI component connected to the HDMI OUT jack on the rear panel of this unit.
CHOICE = OTHER
HDMI component connected to the HDMI OUT jack.
NOTES
This unit transmits audio and video signals input at the HDMI input jacks to the HDMI out jack only when this unit is turned on even if "S.AUDIO" is set to "OTHER".
I'd look in these areas for specific guidance.

I have the same receiver... You can try pressing the Option button and choosing Signal Info to see what audio signal the receiver sees and if that changes over time. Maybe the cable box is not outputting according to specifications... TV can live with that, but receiver maybe can't.
You can also try to connect the cable box via SPDIF cable (optical or coax) to see if it helps or not.

If you're expecting multichannel sound FROM THE TV instead of from the source you're watching, it's not gonna happen. TV's are notoriously poor sound sources. This one is no different.
Multichannel TV-related audio is best found at its source - cable / sat / dvd / bd....
I run video-related audio from my video sources directly to my TV and their audio directly to my receiver. Specialization yields best results.
I'd recommend skipping the Receiver for video, too, as it adds a lot of opportunity for HDMI-related incompatibilities and sound syncing problems. The more interconnects in the path, the more distorted it will become and the more opportunities for problems. Plus you can bypass the receiver and listen to lo-fi programming like news and weather through the TV's speakers if you like. Save a buck on electricity.
Just curious, which HDMI on the receiver is connected to your TV? Input or Output?
This note is on Page 11 of the manual:
Audio signals input at the HDMI jack are not output from any speaker terminals but output from the connected video monitor. To enjoy the sound from speakers connected to this unit,
-- make an analog or digital connection besides the HDMI connection (see page 13).
-- mute the volume on the connected video monitor
================
"Check SP cable." -- The unit is perceiving a short circuit. Are your speaker impedances sufficiently high? Disconnect the Front Right speaker and try raising the volume again. The speaker may be blown or the cable shorting.

Check the settings on your source device, it may be set to send audio as PCM over HDMI, you need to set the audio output on the source device to bitstream or raw.
Note if you are using the original PS3 you need to leave it on PCM as it can not bitstream the HD audio from Blu-ray(the new PS3 slim can do this).
Also Check your PC is really output 5.1 or 7.1 via hdmi.
