Hi,
could I have at least a hint to know if it's to be supported soon, or one day, or never ?
Thanks,
Xav

Even 5.1 (without having to resort to passthrough) would be better than plain stereo. Hi, This is a very old report and this issue is likely to be fixed in the recent kernels. Could you try one, please? There was support for multiple channels added. Sorry I obviously have missed this bug. The audio codec of the RV630 mentioned in this bug can only handle two channels, so the hardware simply doesn't support this. Later hardware generations do support HDMI multichannel audio. |

Hi, using a HD 2600, audio over HDMI is stereo-only. The only mean to have multichannel (e.g. 5.1) is to use passthrough, but true multichannel (e.g. 8 channels PCM) isn't supported by the driver, although it should be supported by the HDMI standard.
