You're not wrong!
What is infuriating is that the original update was, supposedly, being tested for a long time before it was released. That went well, didn't it? It was followed by an immediate update and now this one. Different problems are being reported on each update, many of them making the Aura not fit for purpose.
Update 01.00.60.B
After the factory reset and re-setup last night I turned it off at the mains to give it a long power-down which I do think has a different effect and fired it up this morning and it did!
Once fully rebooted and then turned back on with the other kit I had a HDMI loop trying to establish a picture to the TV but just a black screen and no home screen.
I did a long hold on the power button on the controller and a picture popped up with do you want to shutdown which I cancelled as I now had a picture.
I currently have the Lindy adapter removed.
It had not done this prior to the extra long power down.
The new hot fix affects:
AAC 5:1 works as multichannel PCM and plays.
AAC 2 Channel and possibly Mono too, no sound on video playback on VLC.
All 5:1 video sound is coming out as multi channel PCM, DTS, AC3 (Dolby Digital, Dolby Digital +).
Freeview TV No sound.
BBC Iplayer and YouTube no sound and a Spinning Wheel on the screen sometimes with a frozen frame.
I suspect the centre speaker is now coming out of the left rear and Left rear out of the centre when I play a Dolby digital balance test video , I cant confirm if AAC has the same issue yet.
The test used to work and I used it to balance my system sound , it uses an AC3 5:1 audio track .
I set the Aura audio to the TV setting as Stevo mentioned in the posts and then get stereo sound out of the TV and BBC Iplayer and YouTube and VLC, all play with stereo sound.
The spinning wheel on screen is due to the Audio issue and not network it seems.
I think the TV and Iplayer and Youtube generally use AAC 2 track Audio and the surround sound fix has broken AAC stereo which breaks the apps with stereo sound.
The HDMI CEC changes have allowed me to remove the Lindy adapter, starting up I saw it flash Blue then red then blue as it came on , this was using the Logitech controller bringing kit on in sequence.
USB NTFS fix seems to work as they said and is allowing me to use that format again on my sticks, but I want to test it more to see if there is any side effects.
I can play video in surround but anything in AAC stereo fails or have it all in stereo with no Surround.
I will re-submit the full findings and any more that occur to Humax Support and try to dig out of this rabbit hole.
