Jackpot, this is it. Just tried your patch and now all audio formats are
working. I can confirm that the following formats can now be played back
correctly on my RX480:
- PCM 2.0
- PCM 5.1
- PCM 7.1
- Dolby Digital@5.1
- DTS@5.1
- Dolby TrueHD@7.1
- DTS HD-MA@7.1
- Dolby Atmos
Excellent job. Can we please get this patch into drm-fixes, as it is cleary a
bug fix and not a new feature.
