No audio from my MC700

[journeywego]

How'd,

Unboxed my MC700 today........no audio. I have been reading through many threads, so my apologies if this is covered elsewhere. 

MC700 - Firmware 2.9.3
Speakers Genelec 8020's, Mackie HR624's and a new S12 (all powered)
Display Christie FHD551-X
Sources: Amazon Firestick, Xfinity TV box, Samsing Blue Ray Player, Vintage Nintendo through an analog-HDMI converter

Video sources switching fine, I just don't get any audio out of the RCA's

• When I use the test tones from the MC700 - all working, so the analog side of the system is legit
• Have tried rebooting and varying the reboot order between sources and MC700......... no change
• Just spent some $$ on new 4K HDMI cables which will be here tomorrow, but honestly I don't see how that will make things any better other than having some high end, matching cables. www.amazon.com/gp/product/B06XNRJSSW/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Any thoughts? It's never a great feeling when you pop in a new unit only to have it NOT work right out of the box. (It's not like the CEC is not working as I wish it would.......there is no audio!!!!) 

Did I prematurely sell my Yamaha? Please help.

Cheers!~

OK, so I replaced the HDMI cabling and things are now working.....Happy that its all working, but don't entirely understand.

Once you have some time to refine your set-up you will have to post a summary of your impressions of the MC.

what cables did you put in HDMI?
I have never had any problem with the audio but with the video I have permanent image desynchronization or HDR problem (white veil) even with premium HDMI cable (Supra)
Never had any Audio trouble with HDMI 4k (1-3)
