From: Niraj <[email protected]> Apparently this board seems to need some extra initialization before a proper codec probe value can be read.

Without it, no codecs will be detected. I'm not sure if you like it this way or if you want me or Niraj to change anything, or debug further. Or maybe add a new quirk for this particular device? diff --git a/sound/pci/hda/hda_intel.c b/sound/pci/hda/hda_intel.c index fa2879a..2bf46e9 100644 --- a/sound/pci/hda/hda_intel.c +++ b/sound/pci/hda/hda_intel.c @@ -1306,6 +1306,12 @@ static void azx_init_chip(struct azx *chip, int full_reset) /* reset controller */ azx_reset(chip, full_reset); + if (!chip->codec_mask) { + azx_writel(chip, GCTL, 0x100); + while(azx_readl(chip, GCTL) != 0x0); + azx_writel(chip, GCTL, 0x1); + azx_reset(chip, full_reset); + } /* initialize interrupts */ azx_int_clear(chip); -- 1.7.9.5 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1155202 Title: [Intel DZ77SL-50K, Intel PantherPoint HDMI, Digital Out, HDMI] No sound at all Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: I am using ubuntu 10.04 I expected sound Got no sound at all I am very new to ubuntu so I have no idea how to find the version of the package I am using ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1.1 ProcVersionSignature: Ubuntu 3.2.0-38.61-generic-pae 3.2.37 Uname: Linux 3.2.0-38-generic-pae i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
