    Default Radeon DRM Finally Has HD 6000 Series HDMI Audio

    Phoronix: Radeon DRM Finally Has HD 6000 Series HDMI Audio

    The open-source Radeon DRM/KMS driver in the mainline kernel beginning with the Linux 3.5 release will finally provide support for HDMI audio on the Radeon HD 6000 "Northern Islands" graphics cards...

    Thumbs down Meanwhile ...

    My 7870 still has no HDMI audio with official Catalyst 12.4 on Ubuntu 12.04 LTS.

    That is 6 months after card release and 2 months after OS release.

    My Radeon 4850 has it, but I don't have a sound system or monitor that use HDMI :-(

    So what does that have to do with enabling 6xxx hdmi audio in radeon kms driver?

    The latter is contradictory to the first, and not supported by the [shocked]external link[/shocked] you provided.

    No it isn't. The first means enabling (including) it in code, the second talks about the default kernel config.

    Yes, it is:
    hopefully will allow enabling it by default in the near future.
    But there's still some issue in the Article:

    Doesn't reflect what's written at the block:
    enable HDMI on DCE5 (AKA NI excluding Aruba)
    So it works on Nothern Island except Aruba?
    HD 6950/6970/6990 are Cayman, not Aruba and I don't know any other HD 69XX cards. If I remember correctly Aruba are early HD 7XXX cards.

    Code:
    CEDAR		DCE4		Evergreen
    REDWOOD		DCE4		Evergreen
    JUNIPER		DCE4		Evergreen
    CYPRESS		DCE4		Evergreen
    HEMLOCK		DCE4		Evergreen?
    PALM		DCE4/4.1	Evergreen
    CHIP_SUMO	DCE4/4.1	Evergreen
    CHIP_SUMO2	DCE4/4.1	Evergreen
    BARTS		DCE5		NI
    TURKS		DCE5		NI
    CAICOS		DCE5		NI
    CAYMAN		DCE5		NI
    ARUBA		DCE6/6.1	NI
    TAHITI		DCE6/6.1	SI
    PITCAIRN	DCE6/6.1	SI
    VERDE		DCE6/6.1	SI
    I've compiled table above using RadeonFeature wiki page. According to that Aruba is still Northern Islands, but it is newer DCE6 or DCE6.1. We support HDMI up to DCE5 only, so Aruba is not supported.
