[Bug 665488] [NEW] ALC888 clicks, blobs and stutter with irq sharing

[EricW@Hamburg]

Public bug reported:

Linux agamemnon 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:45:36 UTC
2010 x86_64 GNU/Linux

In my machine the hda-intel kerneldriver is irq shared with 2 ohci usb
controllers, this cannot be solved by bios settings. Sound under windows
is brightly clear, with earlier kernel and the realtek-alsa
driverpackage everthing was fine. With 2.6.35 i cannot compile the
realtek drivers to fix the problem. With kernel alsa the sound creates
click, stutter and blobs like a really dirty cd.

ohci_hcd:usb3, ohci_hcd:usb4, hda_intel

I have located the usb connectors group 3 and 4 and removed everything
from them, the stutter is still alive. This problem exist since 10.04
and could be fixed there with the realtek driver pack pretty best.
