Windows 7 ultimate
Audacity 2.3.0
Audacity has been working for me fine with my ROHS Super USB cassette converter. Then all of a sudden it stopped working. I’ve checked all the recommended settings and they hadn’t changed any and I hadn’t messed with them. I even uninstalled Audacity, re-downloaded and installed it. I reset all the recommended settings and nothing changed. The only thing I can think of, and it doesn’t make sense, is that I ran a tape head cleaner through the cassette but am unsure of the timeline with respect to when it stopped working. Is it possible that it could have somehow demagnetized the heads of the cassette recorder? I don’t see how it could have, but I can’t think of anything else as nothing else had changed. I’ve read everything I could find in the online manual. Nothing just makes sense to me.
The avformat-55.dll is in the Windows/System32 folder.
There’s a gazillion FFmpeg files in the C: drive
I assume that avutil, avcodec and avformat are included in the avformat-55.dll.
Thanks.
