getFolderTrackCount plays file in that folder

[sferni]

When i call the getFolderTrackCount method, a track from that folder is being played for a split second.
This also happens when i insert the SD Card.
I have a MH2024K-24SS from AZ Delivery, bought last week.
I noticed this also happens with other libraries, when i try to get the folder track count.

This is the debug output from the PlayRandom Sketch where i just commented out the dfmp3.playRandomTrackFromAll() and called getFolderTrackCount(0) exactly one time:

The command to get playback mode is returning a value that isn't documented in any spec I have. All the docs I have only have valid values up to 3 and yours is returning 5?
The documentation for this specific command (0x45) is sparse and often missing from chip to chip. I suspect whatever chip version you have they expanded it. This value may hint as some mode that autoplay? Try setting the mode specifically using setPlaybackMode(), but even this command (0x08) can mean different things from chip to chip, some its set playback mode, some its repeat global track.

From the output you provided, I see nothing to suggest that a request to play or even that a play finished happened. It could just be an annoying issue with the chip.
