"No data available" all audio folders, versions after 1.5.2

I'm getting "No data available" on all audio folders using versions after 1.5.2. I went back to 1.5.2 and got everything working again then decided to try 1.7.1.1 to see if that fixed the issue - it did not. So now I have gone back to 1.5.2 yet again. Images and video play fine. My audio files are mp3 and they play fine through v1.5.2 but not all on any version after that. I've tried Sharp Aquos and BubbleUp with Media Player on my Google TV box ... both work fine with v1.5.2 and both give "No data available" on any subsequent versions.

Help!

Can you post detailed log of when you're browsing the audio folders?

I tried installing 1.7.1.1 on another computer and it played the audio files OK through my Sharp TV ... so I assume something has become corrupted on my main computer used for Serviio for many years and many upgrades. When I have time I'll completely uninstall Serviio and start from scratch with 1.7.1.1. It's working fine now that I went back to 1.5.2. I'll let you know if I still have a problem then and send the Log file. Thanks.
