Why doesn't my HDMI audio driver show in sound manager?

I've seen a numbers of posts with problems with HDMI audio on hd2600 mobility radeon, but all the people with those posts are seeing the HDMI sound card in sound manager. I installed the latest driver from ATI but can't see any driver for HDMI. Is there anything wrong with my ATI card?

  1. Is the HDMI sound working or is it just not showing up?
  2. Plug something into it and see if it comes up in Device Manager. If you connect something and it displays a notification and/or shows up in Device Manager, you're all set. :)

    When I install ati catalyst it doesn't show any HDMI sound driver installed, it's like the card doesn't have HDMI sound but in the specs they write this card has a dolby 5.1. I tried with show disc device/ disable device. Nothing . It's like the HDMI sound chip isn't working. does someone had this problem also?

    It doesnt show up. A popup appers that i connected a HDMI-DVI unit and to get sound i should connect another cable from audio card to input sound on the TV. I don't think it's the cable also . I have a DVI-HDMI cable.

    That's probably it just there: you're using a DVI converter. Do you know if the converter supports audio signals? Many don't. Audio capability is native to HDMI but not to DVI.
