You mean like nothing? Zilch? Not even a loud pop on the start/stop of playback?

I have no issues with audio + touchscreen on m28evk since like 3.7 or so (even 
before I pushed the driver mainline), so this is weird. Do you have your 
speakers connected to LineOut or Speaker output from the SGTL5000 ? In case of 
LineOut, is your on-board amplifier on ?

Best regards,
Marek Vasut
