Hi guys!
A question to owners of M5 did you have any issues playing SACD ISO file and have you had problems with media library update?
There seems to be 2 issues with my player:
1 It couldn't handle SACD ISO files properly - on playback there are 2-3 second hiccups every 25-26 seconds of playback on every ISO file I tried, all of these files play nicely on foobar2000.
I tried different files using different microSD cards until (after swapping 3 or 4 cards) player stopped recognizing media files - and this is problem No 2 and the major one now.
2 It doesn't matter which kind of files I throw (mp3, flac, waw dsd, iso etc.) player doesn't see them and updating media library finishes with 0 files found every time now. I tried FAT 32 (as recommended) with capacities from 16GB to 128GB from Samsung, Sandisk, Lexar, PNY none of them work, tried to use exFat as well, and that did not help either.
Surprisingly, inserted card is visible when player is connected via USB (in USB storage mode), and I can access it with no problem at all, so the problem here is not hardware related - pure software. I tried to update firmware to 1.10 - updated smoothly, no issues during update (so it can see cards content, as it reads new firmware file), but newer version coudn't fix library update issue.
It looks to me as if their filtering function is screwed up, as it can see cards file system, and when it tries to update it's library it takes longer to process higher capacity cards with larger number of files on them (with the same result though)
I tried to use it as USB DAC as well, and drivers couldn't install properly and the player itself was not visible as connected audio device, so no luck here as well.
I then was swapping versions 1.0 and 1.10 back and forth, nothing can force it to see music files.
As of now I seem to have $500 USB 2.0 microSD card reader, which is sad, as I had high hopes about it.
While it played files initially - it was really nice sound-wise (apart from hiccups issue)
If anyone had that issue and was able to fix, please share, as I'm out of ideas now except sending it back.
