Ah, that’s an easy one. The Quantum Processor is picking up the audio from the next parallel dimension. Note the characteristic delay caused by the quantization (solar wind byproduct).
That’s not it? Bizarre.
On the serious side, there’s a strong possibility that the audio codec, or some component of your firmware , is corrupted. The fix is easy: The current build of the firmware is 1.01.20. Go (on your Clip) to Settings > Info, and read the first line. If you have anything other than version ‘.20’, the simplest step is to download the Sansa Updater, then plug in your Clip for a rapid brain transplant (new firmware), which should correct the issue.
If you have version 1.01.20, the Updater will see the current version number, and it won’t load another copy. In this case, or any case when the firmware needs to be manually loaded, follow the simple directions in the stickies above. (Look up the “firmware 1.01.20” thread.
This should cure the parallel dimension issue.
