Connect all HDMI to TV and optical to Receiver?

The technical service of my cable company gave me the following suggestion. I am suspicious because I am not an expert.
To get better sound in my 5.1 HT, he suggested to connect hdmi output from the DVD-player to hdmi input to the TV and to connect the hdmi out from the set-top box (cable decoder) to the tv (see my system in my profile) and a toslink cable from the tv to the receiver. He said that the optical would carry only audio signal for a better resut. Does this make sens ?
Actually, my connections are dvd and set-top to the receiver and from the recever to tv one hdmi.

It will work but one should do that only if absolutely necessary. Keep it the way you are doing it. Typically, feeding the sound through the TV will limit the format options available to the receiver. Also, there is no inherent advantage of toslink in this situation.

what Kal said. unless you're getting artifacts in the audio or glitches I would keep it the way you have it. you it's illogical. you can test it out and A/B the results to see if it's better, but unless you're having issues that makes no sense

Just curious as to when it does offer an advantage?

When you need galvanic isolation, I guess.

Can’t speak for this particular connection scheme (the one proposed by the cable company), but I’ve seen plenty of situations where HDMI to the receiver and then HDMI to the TV resulted in drop-outs in the audio with some components. Adding a toslink or S/PDIF connection eliminated the problem.

Regards,
Wayne

Also note that optical will not carry the Dolby TruHD or DTS Master audio signals. So from the cable box that is ok but the Bluray player you will loose the uncompressed audio.

Home theater:
Onkyo 805, Yamaha YDP2006EQ, Samson Servo 600 amp
3 EV Sentry 500 monitors across the front, 4 Mission 762i's Surrounds, SVS PB13U sub, Panasonic BDT220, Harmony 1100, Nintendo WiiU
Panasonic PT-AE8000 on a 120" 2,35:1 fixed screen

Living room system:
Sherwood/Newcastle R972, Mission 765's, SVS SBS02's, A/D/S MS3u sub, Yamaha YDG2030EQ
Yamaha KX-393 Tape deck, CDC 805 CD changer, Panasonic BD60, Sony turntable PS-T20
Panasonic TC-P50ST60, HD-PVR & WDTV Live, Harmony 900
