funman:
The playback stopping is a bug in buffering, not in clocking.
The clock speeds are the same on all other Sansa AMS models.
You can trigger the bug by using an even smaller audio buffer (using static unsigned char[A_LOT]; in firmware code for example)
breno:
I've noticed you have made some changes regarding low ram devices like mine in the latest releases. I've compiled the r22249.
Music playback is still the same, mp3 plays for a second them stops and flac dont even plays anything. After trying to play something i still can go back to the menu but the activity icon stays on and i cant do anything else (like going to fm radio) - this was already like this in previous builds, im just explaining how it is working on my c240v2.
FlynDice:
I posted FS#10507 to flyspray tonight which lets me run my uSD card at 31 MHz which is within the SD specs. I also ran it at 15.5 which would be the non-highspeed setting and it ran fine.
EDIT: Nevermind, this does not run at the lower freqs, the bypass bit is still set... :-\

If there is a bug in buffering, the frequency of runtime error caused by this bug depends on
clocking and audio buffer size. Difficult for me to understand why clocking has an effect.

He said clocking isn't related to it.
Did anyone try flyndice's patch with the problematic microsds, or impact to transfer rate?
