So if you have a reg editor(like PHMregedit), here's the long and short from my notes ...
**** To resolve skipping audio ****
Need to change
BlockTransferSize which specifies the maximum amount of blocks to send per bus transfer.
[HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Cl ***\SDMemory_Class]
[HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Cl ***\MMC_Class]
Change the value of BlockTransferSize in each class from the default of 64 (0x000040) to 32 (0x000020).
Hope this helps ...
Cheers
