It seems your TV refuses to use audio from analog stereo cable, when it detects audio enabled over/in HDMI (just enabled, even purely silent as in your case). And it seems we enable HDMI mode even when you use radeon.audio=0. I've no idea what could affect this between 2.6.33-rc8 and 2.6.33 (stable). The list of changes for drm/radeon taken from http://lkml.org/lkml/2010/2/24/301 : Adam Jackson (1): drm/edid: Fix interlaced detailed timings to be frame size, not field. Alex Deucher (3): drm/radeon/kms/rs600: add connector quirk drm/radeon/kms: fix shared ddc detection drm/radeon/rv740: fix backend setup Dave Airlie (3): drm/radeon/kms: make sure retry count increases. drm/radeon/kms: use udelay for short delays drm/radeon: bump the UMS driver version number to indicate rv740 fix Jerome Glisse (3): drm/radeon/kms: fix indirect buffer management V2 drm/radeon/kms: fix bo's fence association drm/radeon/kms: free fence IB if it wasn't emited at IB free time Matt Turner (1): drm/radeon/kms/atom: use get_unaligned_le32() for ctx->ps Can you provide "lspci" output by the way? As for this bug, I'll try to prepare something for you to test. However provide also output of dmesg | grep drm please. -- Rafał ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
