Hi folks,
How is the audio quality that you get via the 3.5mm jack?
Thanks.

For which device are you asking? Pine builds several products with a 3.5mm audio jack, AFAIK.

Edit: Moved the thread in the right section.

Ooops sorry. Pinephone and Pinephone Pro. I'm wondering the about quality of those. Also, if there is a DAC or amplifier.

Pinephone uses the built in headphone output of the A64 via a BCT4717 analog switch chip between it and the headphone socket to switch it between headphone and serial port use. The closest I've seen to measurements is this thread, which started with some measurement errors, and lacked sufficient detail of things like mixer settings to be sure the final result was representative.

I haven't checked the Pinephone Pro schematics, but you'll find the link in the wiki.
