It doesn't work for me, and sorry but I'm too dumb to fix that :( Playback speed in mplayer is alright, but my AV doesn't get any audio signal. --- kms.playing.broken.dump.log 2009-09-28 16:06:00.000000000 +0200 +++ radeonhd.playing.dump.log 2009-09-28 14:21:51.000000000 +0200 @@ -5,8 +5,8 @@ 0x0518: 0x00E297D0 0x051C: 0x00000000 0x0520: 0x00000070 -0x0524: 0x00249F00 -0x0528: 0x008719F0 +0x0524: 0x00000000 +0x0528: 0x00000000 0x052C: 0x00000000 0x0530: 0x00000070 0x0534: 0x00000000 @@ -24,7 +24,7 @@ 0x7388: 0x00010001 0x738C: 0x00020002 0x7390: 0x00000001 -0x7394: 0x00020070 +0x7394: 0x00060040 0x7398: 0x00000001 0x739C: 0x00000009 0x73A0: 0x00000201 It seems KMS set also second pair of registers, probably for my LVDS (PANEL). No reason for that, but shouldn't hurt, right? I don't know meaning of R600_AUDIO_SUPPORTED_SIZE_RATE (0x7394) is this something important? I've tried rhd_dump -w 0524: 0x00000000 1:00.0 rhd_dump -w 0528: 0x00000000 1:00.0 rhd_dump -w 7394: 0x00060040 1:00.0 but it didn't help. It reminds me RV770 issue from radeonhd, where we don't get working audio. All registers are 100% alright, but no sound. Maybe order of setting registers matters? Do we set registers in different order than radeonhd does? Please, check attached log files. In both cases I've started playback *just once*. In case of radeonhd there is one RHDHdmiUpdateAudioSettings operation. However KMS prints 4*playing messages. -- Rafał
