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.

Here's the excerpt from alsa-info.sh concerning the card:
