Hello,
Does anybody know how to fix the no-sound bug for a Discover Pro (mib1) .
The unit is a 5G0035043D and has fw MHIG_EU_VW_K1550.
When you go to software update and select the sd card for a search of new firmware, while searching press back(cancel) the sound is back until the next reboot.
Discover PRO - No Sound
Hi Theed,
I know exactly this problem. It was the same at the Audi versions 8V0xxxx MIB1 have.
A well known issue has something todo with a defectiv cooling fan, which is the failure variant happened a view minutes after usage.
But I even know the failure, at a cold unit. Nothing todo with overheating the audi amp... It would be great to find a solution for me too.

I finalized my investigations on it:
1. There is a small group of very early MIB1 Units, which have a software bug which generateds a wrong mute-signal. A SW update fixes it.
2. Most of the defective units have hardware problems with weak solderings and/or defective power amp ICs.
The defective ICs are very bad to buy on the global market. It takes lot of time to find.
In all cases, I can offer a repair for defective units.
