attached is the new version of my HDMI patch wich should apply cleanly to current git master.
Right, I have also tried this patch (plus patch number 0002). System is Alpha architecture, with HD 2400 Pro card, RV610, which admittedly doesn't match the list of compatible hardware given for the patch, but thought I'd try anyway. I used the option "all" on the HDMI option in the Xorg.conf file for the radeonhd driver. Once I realised I needed the snd-hda-intel kernel module (for which I selected only the generic and ati kernel module options when compiling it), I then found the ATI HDMI alsa sound device. I don't have any HDMI aware receivers so can't properly test it, but I did try to play sound files through the ATI HDMI device with the alsa aplay command. I verified that the sound files (signed 16bit, 44.1kHz, pcm) would play through my other sound devices (on board sound chip, and a cheap surround sound card), but aplay would hang and not return when playing via the ATI HDMI sound device (was breakable with ctrl-c). Examination of /proc/interrupts revealed that interrupts were not clocking up for the ATI HDMI interrupt. This is evidence that things are not working as they should. As my ATI card has only DVI-I, VGA and TV-out connectors, I presume that HDMI output appears on the DVI-I connector (since they are electrically compatible), and one must use a DVI to HDMI connector to connect to some HDMI aware receiver? I also guess that the HDMI audio output is in digital format, so that one needs an HDMI signal decoder and DAC to play the sound (i.e. the HDMI receiver). Is my surmising correct?
