Hi,
I encountered the same issue this week…
After numerous checks, tries, restores on several disks, I solved finally the issue in reapplying the AUDY54C.MEM file.
- Check this file is present in C:\
- Reboot with the 2 buttons F10 and UNPLUGGED down
- Accept the warning message
- During about 5 minutes your keyboard will be flashing then Audya automatically reboots.
This simple method corrected all my problems. In fact, we think that we have a disk issue. But, it's a mistake. The issue is within the BIOS or the RAM. Reapplying the OS is the only thing we can do to reach RAM and BIOS.
If you have a backup ready, it's a minimal risk.
In my opinion, I will no more connect the Audya with Midi Host plug to reach the internal disk. USB connection is too unstabled. If I need to, I dismount the disk and connect it directly to my PC…
It's my experience. If it can help….
