This is a note to let you know that I have just added a patch titled ALSA: hda - Disable 64bit address for Creative HDA controllers to the linux-3.13.y-queue branch of the 3.13.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11-ckt31. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 2de0a8ef3f735ccaf43216706ff089c0f8adf899 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Tue, 27 Oct 2015 14:21:51 +0100 Subject: ALSA: hda - Disable 64bit address for Creative HDA controllers commit cadd16ea33a938d49aee99edd4758cc76048b399 upstream. We've had many reports that some Creative sound cards with CA0132 don't work well. Some reported that it starts working after reloading the module, while some reported it starts working when a 32bit kernel is used. All these facts seem implying that the chip fails to communicate when the buffer is located in 64bit address. This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT flag to the corresponding PCI entries. I casually had a chance to test an SB Recon3D board, and indeed this seems helping. Although this hasn't been tested on all Creative devices, it's safer to assume that this restriction applies to the rest of them, too. So the flag is applied to all Creative entries.
