Description Tom Yan 2013-10-20 03:41:49 UTC

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?
