Priority: medium
Bug ID: 70660
Assignee: [email protected]
Summary: ATI R6xx HDMI Audio only works with 44.1KHz
QA Contact: [email protected]
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: 7.7 (2011)
Component: Driver/Radeon
Product: xorg
I am using an Evergreen (HD5850).
Actually I also seem to be able to have sound when the sampling rate is
mutiples of 44.1KHz(22.05, 88.2, 176.4), but not 48KHz(96, 192). 32Khz doesn't
seem to work too. The reason I use "seem" is because I am not sure if there is
any software resampling done for those multiples.
And I have tested this in mutiple environment: Pulse, pure ALSA, jack, the
result is all the same. So I am quite certain that it's not some issue caused
by setting (at least not a "high level" one).
But is the open source driver suppose to work with 48/96/192KHz yet?

FYR, some of my observation that MIGHT help. (How stupid I am to make duplicate
like this.)
P.S. I've also tested with hwac3 in mplayer. 48KHz is also silent, while
44.1KHz AC3 can produce some sort of (loud) "clicking noise". Btw is AC3
passthrough suppose to work yet?
