Hello merlin.
I have foung a similar problem with my mp3s on my Humax 1100s.
Initially I assumed the conversion values were incorrect.
Codec:- MPEG Audiolayer 1/2(mpga)
Channels:- Stereo
Sample Rate:- 44.1 kHz
Bits per sample:- 32
Bitrate:- 128kb/s
I had one file that played, another that didn’t.
I checked the File Names, “04 Dancing Queen.mp3” played fine.
“Track 04.mp3” didn’t
“Solid.mp3” also played fine.
The “Permissions” are set to “Allow”
I’m running out of permutations.
I’m missing something fundamental perhaps?
Regards James
