[alsa-devel] snd-hda-intel: Is there a way to specify a quirk for the default bdl_pos_adj value for the given chipset (PCI ID)?
Hi!
I'm working on a patch against GIT for snd-hda-intel that would let my card's capture work properly without losing ability to capture audio (that's an old story available in this thread: http://thread.gmane.org/gmane.linux.alsa.devel/66775).
I know how to make position_fix=1 permanent for the given PCI ID (the snd_pci_quirk position_fix_list struct array in hda_intel.c), but there seems to be no way of making a similar quirk for bdl_pos_adj - am I looking in the wrong place?
My work on a patch goes in parallel with determining the minimal set of modifications that will solve the problem.
Currently, I've determined that the combination of 3 module options described in this forum post solves my problem: http://www.linuxhardware.org/forums/viewtopic.php?p=66&sid=f6e8953338fd9...
I'm working on isolating the minimum set of these that solves the problem (which requires a couple of hours to be reproduce, so that takes time).
I've observed that neither position_fix=1, nor bdl_pos_adj=0 solve the problem by themselves in isolation.
I'm unsure whether model=3stack-6ch is necessary at all, because patch_realtek.c already has the model mapping for my combination of PCI IDs and it maps to a different model: SND_PCI_QUIRK(0x1458, 0xa002, "Gigabyte P35 DS3R", ALC882_6ST_DIG),
Once the minimization is accomplished, I want to prepare a patch against GIT (git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git is the repo to work against, as far as I understand).
But since it seems that bdl_pos_adj=0 is required for proper operation, I need a method to map the default for that option in the sources, if there is such a method.
I'd be grateful for any pointers.
