Hi,
from v4.18 to v4.19-rc1 there is this commit
75b31192fe6ad20b42276b20ee3bdf1493216d63
ASoC: rockchip: add config for rockchip dmaengine pcm register
which broke hdmi audio on rockchip.
Now testing v4.19-rc4 which this single commit reverted and it works ok.
As shown in below logs, there is no evidence of the breakage from dmesg.
"aplay -l" also shows no issues, but pulseaudio does not detect the
sound card.
When testing with "aplay -vv *.wav" it works fine with the commit
reverted, but otherwise, aplay just uses pulseaudio's dummy output.
Regards,
Vicenç.
