[alsa-devel] [PATCH RESEND] ASoC: arizona: Do not create OUT4R widget for CS47L24/WM1831
by Richard Fitzgerald 27 Apr '16

27 Apr '16

The CS47L24 and WM1831 codecs only use the OUT4L widget so we can skip creation of the OUT4R widget.

From: Matthias Reichl <hias(a)horus.com> Register as a custom pcm device with the correct settings supporting also 16 bit. The automatic pcm discovery does not enable 16 bit modes because of a percived mismatch between the dma controller only supporting 32 bit transfers and the requirement by the HW to only support exactly 2 channels, which effectively results in a minimum size of 32 bits, which matches the dma controller transfer width.

[alsa-devel] [PATCH v2] ALSA: hda - Update BCLK also at hotplug for i915 HSW/BDW
by Takashi Iwai 26 Apr '16

26 Apr '16

The recent bug report suggests that BCLK setup for i915 HSW/BDW needs to be updated at each HDMI hotplug, not only at initialization and resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at ELD notification, too. Otherwise the HDMI audio may be out of sync and played in a wrong pitch. However, the HDA codec driver has no access to the controller registers, and currently the code managing these registers is in hda_intel.c, i.e. local to the controller driver. For allowing the explicit BCLK update from the codec driver, as in this patch, the former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA controller driver and intel_pin_eld_notify() in HDMI codec driver. Along with this change, snd_hdac_get_display_clk() gets dropped as it's no longer used.
