(Raspbian) Jack Audio com erro estranho

[Lerub]

Meu x86 foi pro saco depois de uma falha elétrica e só deu para comprar um Raspberry Pi 400. Eu preciso do Jack para usar um editor de audio  multipista e estou com trabalho atrasado.

 

Non ALSA mixer não aparece os controles do HDMI. Só o Pulse. E o audio é mono. Mas aí pode ser por eu estar usando um conversor de micro-HDMI para VGA. O JACK só inicia quando seto o microfone USB como... playback(?).

 

Log do jack:
