If you get clear audio when close to the receiver, it would appear to be a problem in either the antenna or the receiver. Try a different antenna or relocate the antenna. If you adjusted the VSWR low it doesn't mean the power is radiating correctly. Verticals should be on roof, with roof as ground plane. Mounting on mirrors is ok, but doesn't work as well. Also, if you have sheet metal near the antenna, it acts as a ground reflector and can distort or block the waveform. You might also try it with a different receiver, in case yours has a faulty pre-amp stage. It could also be a power amplifier problem in the transmitter, where it shows 5 watts but isn't putting out that amount. You can check it with an RF watt meter.

Bad DSP chip. The only other possibility is if you have the "Direct" on. On the front of the receiver it's a small button. Also make sure your "Speaker Select" A/B is "on" You will see it on the display, it's also a small button on the front of the receiver. If all this is correct and you still have no audio, it's a bad DSP chip. Not worth repair, it's 400-500 repair. Not very common in a Yamaha RX-V series, but I have seen it. I'm a Yamaha Dealer. If you need further help, post a comment and I will be glad to help you further.

look for a broken or cracked board near the driver s & finals, try pushing around on the board with your plastic screwdriver, you may luck into it.
