Since i flashed my image from USB version VTI 6.0.1, by some channels when switching I hear awkward wheeze in high sound frequency. I use scart, and direct R+L connected to the analogue amplifier sockets ( cinchs ). Amplifier is connected with 3-way floorstanding speaker system. Regardless on updates problem persist. But only some channels are affected.

I noticed that when I switch to the next channel and back the sound is clear. To better understand: the creepy sound is continuous and is similar like overburned recording of the song.

What can cause this problem?

If this was somewhere in the forum already solved please let me know.... ?-(

@ schomi
Dolby Digital Downmix= On?...........................YES
All VTi Blue/Green/Green Updates? .................YES
@tonskidutch
what's the type of connection between VU+ and the Pioneer...?.......analog ( from the rear side of the VU+where are three cinchs White(L)+Red( Right)+Video )
it looks like a handshake issue and HDMI version issue between the partners.....I still use CRT TV

try sp-dif optical to pioneer and no hdmi + hdmi to Television ... this is older amplifier with no SPDF support

But the problem is that audio signal from SOLO goes from two separate ways ( audio/video cinch output) and SCART output, and both are wheezed. That sounds after some software issue..no?
Funny is when I switch the channel, which is wheezed and than the next and back....no wheeze. To be clear ....choose channel 5-wheezed, than 6 and back to5 ... no wheeze. So what to do. Till now nothing like this.

Did not help anything. Even if sometimes mediaplayer start to play some movie the same sound problem. I have to stop playback, again start to play movie and than it is OK.

Ok, nothing have been changed from VTI version 5.x.x. No cables, no amplifier, no changed socket. The strange sound happen only when moved to 6.0.0 and higher.
I do not want to annoy forum with my personal wheeze problem. The main question is if could it be the software problem? And where to start search first. All hardware have been checked twice before asking here.

Did not help anything. Trying to live with that. Actually i am spending not much time with TV so, it is not as critical. Channel selection up and down is solution for now.

Actually it changed itself with new image version. Now is back to normal.
