Hi
We run Android Oreo 8.1 on our FireFly-RK3399 Boards in our Labs at the University.
Everything runs smooth except the audio part is not working.
There is no sound on the headset HPOx and also on the speaker SPOx output.
It seems that device tree is ok and the audio drivers are installed.
130|rk3399_firefly_mid:/ # cat /proc/asound/cards
0 [rockchiprt5640c]: rockchip_rt5640 - rockchip,rt5640-codec
rockchip,rt5640-codec
1 [ROCKCHIPSPDIF ]: ROCKCHIP_SPDIF - ROCKCHIP,SPDIF
ROCKCHIP,SPDIF
2 [rkhdmidpsound ]: rk-hdmi-dp-soun - rk-hdmi-dp-sound
rk-hdmi-dp-sound
How can I fix that problem?
Is it more a Linux problem or in the Android part?
Many thanks and Regards
Martin
