Regarding Consoles ...Everyone wants to make console ICs, because they not only deliver the most bang-for-the-buck, but the margins are better. Instead of PC CPUs/GPUs that run, at best, 100K-1M units before they are rev'd every 9-18 months, consoles are 10M+ units for 24-36 months before a minor, and I stress minor, rev.
AMD really nailed it getting both the XOne and PS4 with their, although 2013-era, dual-package Jaguar (2x4 L3-less Proc15h, 2x Radeon 8300). We'll see if they stick with AMD for the next, major revision. Right now the new XOne just ships an updated Beema with a bit more ooph and reduced power.
Regarding AVRs ...My living room has a sub-$300, "open box special" ($599 list) Okoyo 7.1 HDMI (although only 1.4, not 2.0) setup. But in my small, 10x10' (3x3m) 'man cave,' I bought a pair of these Pioneer HTS-GS1 units for US$99 (yes, 1/4th list) new back in the mid '00s, and are still using them for my PlayStation/Xbox + PC setups ...

http://www.pioneerelectronics.com/PUSA/ ... ms/HTS-GS1The biggest pain with ToshLink on the PC isn't that the ASIC's don't do them. It's that the encoding is done in software, and the on-mainboard audio, typically RealTek ALC8xx, doesn't include the license. I hacked in a modified DLL and configuration file to get my ALC892 to work on my old Z97, but the hack doesn't work for newer boards/chips.
