Is it possible to downgrade the PicoPix 320 firmware from v1.07 back to v1.04?
The internal speakers worked fine out of the box on v1.04, but after updating to v1.07 it stopped working. Mirroring the phone, connecting via an HDMI adapter, connecting to another media stream via HDMI or using a USB drive with the included cable no longer produces sound from the internal speaker. The video still works and sound can be output through the 3.5m jack. Any suggestions on a possible fix for this issue?
