I updated to CM11 nightly 12-26 last week and ended up losing all speaker function. I've done nandroid restores, factory resets, different roms, and even flashed back to OTA 4.3. I can still make and receive calls fine, and when I plug in headphones they work fine also. I've found a few other treads mentioning this sort of issue with the HTC one but none of them went anywhere. I am S-Off/Unlocked using Rumrunner and running CMR for recovery. I've tried Z-Device test and it says the speakers are fine...I'm not sure where to go at this point.
