Can you test it with radeon driver disabled? (Using fail-safe video/VESA). I have the same issues while using with radeon driver. Using with VESA driver the problem disappears.

comment:3 Changed 11 years ago by thomasmansfeld

When using fail safe-video mode my system hangs at start up. Removing the radeon driver lets the system start. But then I get no sound at all anymore. Seams that switching to the new device manger causes problems with my system: no boot until I remove all USB devices. Panel resolution is not atomically picked ( was before ) at first start.

Moving the mouse improves playback, but still stuttering. Maybe an interrupt related issue.

comment:5 Changed 10 years ago by Adek336

Perhaps editing the file ~/config/settings/kernel/drivers/kernel, uncommenting the line

#serial_debug_output false

(and rebooting) helps, as someone in another audio stutter related ticket noted.

Tried this also, but it didn't help. I think, I have to wait for the fix of ticket #5.
