DVI-D is a digital VIDEO connector, it doesn't carry audio. The audio codec hardware on Radeon outputs through the HDMI connector only, if your laptop doesn't have one but your Radeon is happy to provide you an output sink, that's your problem, and the correct solution is indeed to disable the Radeon audio with "radeon.audio=3D0". --=-E8VcQc2rgWU0lO/crJ9F Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) iEYEABECAAYFAkuECJYACgkQGcb56gMuC61tFQCdGHnXkuesuE6EpOW+/ArGRGiI YM4An3c5ebltuNBu3NBNyXWiVhfUDkUF =4DTe -----END PGP SIGNATURE----- --=-E8VcQc2rgWU0lO/crJ9F-- --===============4590322045908248602== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
