Hello Alex and Maruthi, I'm trying to get HDMI audio working on a AMD CARRIZO laptop, which I believe need the ACP changes which got merged into Linux 4.6. But testing the v4.6 tag, amd_acp_hw_init() returns -ENODEV, because it succeeds the "if (acp_mode != ACP_MODE_I2S)" test in acp_hw.c. Does this mean this chip does not uses ACP, or is there anything else missing? lspci shows me the following gfx/audio devices (I believe this is a dual-gpu machine): 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 9874 (rev c5) (prog-if 00 [VGA controller]) 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Device 9840 00:09.2 Audio device: Advanced Micro Devices [AMD] Device 157a 03:00.0 Display controller: Advanced Micro Devices [AMD] nee ATI Sun [Radeon HD 8600M Series] (rev ff) Both amdgpu and radeon get automatically probed. Sorry if I'm missing something obvious here, I'm quite new to dual-gpu machines. Thanks and best regards, -- João Paulo Rechi Vita http://about.me/jprvita _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
