Audio is fine in Zgemma H9 Combo with PurE2 v. 6.5! My wife and I use it every evening to watch something together.
It's a really FINE MACHINE!!!! And we test it all the time, DVB-S/S2/S2X/T2 and IPTV stuff. It functions really WELL!
I have SATA HDD and USB stick plugged in, configured well and all the images I have in it are really fine!
OpenATV on first partition, then 3 different versions of PurE2 - it's simply great!
And if it weren't I'd be the first to say it! ;)
