Anyone who is using the analogue/headphone socket on the Pi, please try the new sigma-delta audio driver.
You need these settings in config.txt

Code:

disable_pvt=1
force_turbo=1
audio_pwm_mode=2
audio_sdm_mod_order=2

More details here: https://www.raspberrypi.org/forums/viewt...9&t=136445

(be aware that force_turbo in conjunction with over_voltage may set your warranty bit - disable overclock first if you care).

That will need a manual firmware update for now - but that will be in tonight's build.

Tried this last night as one of my 2 RPi2 devices is hooked to an older TV without HDMI. The audio did strange things with pitch/speed. I tried with both PLL adjustments on and off and in both cases the audio pitch/speed was all over the place (sounded like a whammy bar). For now, I've gone back to the previous audio configuration.
