Issue #4043 provides Raspberry Pi 4 hardware, Raspbian, kernel, firmware, and package versions but names no source file or test. Start by reviewing the reported two-screen and 3.5 mm audio configuration against the Raspberry Pi Linux kernel support, then establish whether the combination is supported and document the confirmed outcome.

Description

Before the last Raspberry update/upgrade I had 2 sceeens running and using the audio jack at the same time. Bug reports on the Raspberry forum did not give anything else that I had to wait for a new upgrade and firmware. Some mentioned that 3 outputs would not be possible before kernel 5.10 arrived. Further it is mentioned that the current RPI software only support 2 outputs.

Data

Distribution: Raspbian GNU/Linux 10 (buster)

Kernel version: Linux 5.4.79-v7l+ armv7l
