This is report from version I build locally from sources by Python 3.6 and local lifxlan build (from 1.2.5) https://www.virustotal.com/gui/file/7604ce5398e2eb32abe2527f50bda73198467cce414546854aa99550b93a60d4/detection This is not a surprise that software that grabs the...

@LokoGD I think you should start with a creating the new issue with describing your steps and environment. And we will try to help you there. Because hijacking the other...

Definitely MS AV have joined the party https://www.virustotal.com/gui/file/b69c1eb90cd89c80adb869ff0279b4af79fc3c878215fc88e9b53f0146966473/detection But my Defender keeps calm (security intelligence version: 1.309.1040.0), I also have scaned distr folder of the latest version of local build....

FYI: my local build result has flaged only by 6/67 (but different AV products) https://www.virustotal.com/gui/file/ff1177163fb95c3c0e230b0123d9d2dd21251a307517ce6b5df98d47e09598c9

@fneuf How far as I know PyAudio can't record the output directly. Possible workaround is to use loopback input device which _may be_ featured by audio driver or can be...

I'm trying to localize the issue. A quick look on the FW implementation and codec datasheet shows that USB Alternate Setting is used to control the DAC output: https://github.com/ploopyco/headphones/blob/9c036f07f8d47d243013f6c612e7d7b372aca7f5/firmware/code/run.c#L771-L779 Setting...

Notice that normal signal average (DC offset) is different from Vcom during the shutdown. This is probably the cause of the issue that produces audible pop.

@george-norton yes, 64-register control looks correct. I guess my next step is to dig into FW. I wonder is it possible that Q-band filtering calculations can cause a DC-offset by...

@george-norton as a firmware workaround I implemented debouncing on DAC power mode (https://github.com/george-norton/headphones/pull/2)

Also measured DC offset on the amplifier. DAC output: 2.297V@L+, 2.28V@L-, 2.351V@R+, 2.363V@R-, and of them about 2.29V in Power Save move DAC power: 4.62V@VCC, 2.30V@VCOM Headphones output: 97mV@L, -64mV@R...
