Last e-mail for today (well, it's only 25 minutes left here ;) ). I've
decided to give fglrx a chance (12.4).

1) RV620 connected directly to Sony BRAVIA KDL-52X3500
[   234.399] (WW) fglrx(0): Incorrect HDMI dongle found, HDMI audio disabled.
I couldn't play anything.

2) RV620 connected to Onkyo TX-SR605
Audio playing, but fglrx set 0x7408 to:
0x10020011
so it seems fglrx isn't using
HDMI0_AUDIO_SEND_MAX_PACKETS == 0x100
Setting that bit while using fglrx broke audio.


I did one more test with a different TV: Sony BRAVIA KDL-40S40xx. The
results are the same. fglrx sets 0x7408 to: 0x10020011 (so
HDMI0_AUDIO_SEND_MAX_PACKETS is not set). Setting that bit manually
(while using fglrx) breaks audio.


It just seems to me we shouldn't set that bit at all...
