Description
I have so far not managed to get any HDMI audio from my TV via R9 285.
I can get HDMI sound when connected to a monitor (with cpu load)
With other h/w this TV has recently been OK with a bit of messing around eg. extra run of xrandr + cpu load for R9 270x. RS880 and rv770 worked without the cpu load.
Added complication since getting a new mobo I sometimes get i2c edid read fails on the TV - but then it's not always and the rv770 produced them and worked and the tonga always works for sound with the TV in windows.
I noticed that for the TV the eld does not match what edid decode reports - it only shows one sample rate and shows "Fl/Fr C" when it's only 2 channel. TBH I don't know what eld said historically with different h/w.
edid-decode and eld for TV attached.
