Did Tata Sky solve the HDMI 5.1 audio problem? I thought you could only get 5.1 sound by connecting an optical or coaxial cable. As far as I knew, HDMI output on the Tata Sky HD+ box was not giving out 5.1 audio output.
I believe your AVR has a coaxial input. Don't bother BUYING optical, fragile cables. Just use any spare RCA cable to connect the coaxial output and you should be good till TS resolves 5.1 audio issue through HDMI.
I have connected my Tata sky HD plus to Denon 1909 thru an optical cable as HDMI is useless.
However for SD channels which do not have a 5.1 audio, I hv connected the TV (Samsung D550) thru an HDMI with the TS set top box
