[alsa-devel] Plugged in headphones ignored
by Paul Menzel 27 Jul '19

27 Jul '19

Dear Linux folks, On a Dell OptiPlex 5040 with Linux 5.2-rc6 plugging in a head phone into the front case connector, it is detected just fine and Xfce shows a notification. Then logging out, turning off the monitor connected over DisplayPort at the end of the day, and turning the monitor back on the next morning, logging in, the state is forgotten. I need to unplug the head phone and plug it back in. Please find the output alsa-config.sh for the non-working (1) and replugged (2) situations attached. Is that a Linux kernel problem, or a user space issue? Kind regards, Paul

[alsa-devel] [PATCHv2] hda: Fix 1-minute detection delay when i915 module is not available
by Samuel Thibault 27 Jul '19

27 Jul '19

Distribution installation images such as Debian include different sets of modules which can be downloaded dynamically. Such images may notably include the hda sound modules but not the i915 DRM module, even if the latter was enabled at build time, as reported on https://bugs.debian.org/931507 In such a case hdac_i915 would be linked in and try to load the i915 module, fail since it is not there, but still wait for a whole minute before giving up binding with it. This fixes such as case by only waiting for the binding if the module was properly loaded (or module support is disabled, in which case i915 is already compiled-in anyway).

[alsa-devel] [PATCH v2 0/5] ALSA/HDA: abort probe when DMICs are detected
by Pierre-Louis Bossart 27 Jul '19

27 Jul '19

This is the second take on same problem of detecting when the HDaudio legacy driver can be used and when the SST or SOF drivers are required. The previous attempt based on a the PCI Class information was a resounding failure and broke audio on Linus' laptop, so we need additional information to avoid enabling a DSP-based driver without a good reason to do so. This patchset suggests the use of the NHLT information which *in theory* exposes DMIC endpoints. The legacy HDaudio driver cannot handle DMICs and will not provide any capture capabilities. Since it's typically the first one to probe due to the Makefile order, aborting the probe will let the PCI subsystem look for the next driver which hopefully will support this capability. I tested this patch on 5 devices (SKL, KBL, APL, GLK, WHL), three without DMICs and two with, and the detection seems to work as planned. Additional testing by Canonical and Endless folks did not expose any issues. Changes since v1 (Feedback from Takashi): Squashed patch3 in patch2 Changed log to dbg_info Fixed module parameter handling Changes since RFC: Cosmetic code improvements Moved intel-nhlt.h to include/sound Moved intel-nhlt.c to sound/hda Removed SOC prefixes Added full-support for vendor-defined geometries Added Kconfig and kernel module parameter to opt-in Pierre-Louis Bossart (5): ASoC: Intel: Skylake: move NHLT header to common directory ALSA: hda: move parts of NHLT code to new module ALSA: hda: intel-nhlt: handle NHLT VENDOR_DEFINED DMIC geometry ASoC: Intel: Skylake: use common NHLT module ALSA: hda/intel: stop probe if DMICS are detected on Skylake+ platforms .../skl-nhlt.h => include/sound/intel-nhlt.h | 51 +++++++-- sound/hda/Kconfig | 3 + sound/hda/Makefile | 3 + sound/hda/intel-nhlt.c | 102 ++++++++++++++++++ sound/pci/hda/Kconfig | 10 ++ sound/pci/hda/hda_intel.c | 34 ++++++ sound/soc/intel/Kconfig | 1 + sound/soc/intel/skylake/skl-nhlt.c | 91 +--------------- sound/soc/intel/skylake/skl-ssp-clk.c | 1 + sound/soc/intel/skylake/skl-topology.c | 1 + sound/soc/intel/skylake/skl.c | 12 ++- sound/soc/intel/skylake/skl.h | 4 - 12 files changed, 205 insertions(+), 108 deletions(-) rename sound/soc/intel/skylake/skl-nhlt.h => include/sound/intel-nhlt.h (65%) create mode 100644 sound/hda/intel-nhlt.c -- 2.20.1

[alsa-devel] [PATCH v2] ALSA: i2c: ak4xxx-adda: Fix a possible null pointer dereference in build_adc_controls()
by Jia-Ju Bai 26 Jul '19

26 Jul '19

In build_adc_controls(), there is an if statement on line 773 to check whether ak->adc_info is NULL: if (! ak->adc_info || ! ak->adc_info[mixer_ch].switch_name) When ak->adc_info is NULL, it is used on line 792: knew.name = ak->adc_info[mixer_ch].selector_name; Thus, a possible null-pointer dereference may occur. To fix this bug, referring to lines 773 and 774, ak->adc_info and ak->adc_info[mixer_ch].selector_name are checked before being used. This bug is found by a static analysis tool STCheck written by us. Signed-off-by: Jia-Ju Bai <baijiaju1990(a)gmail.com> --- v2: * Fix the errors reported by checkpatch.pl.

[alsa-devel] [PATCH] ALSA: hda - Show the fatal CORB/RIRB error more clearly
by Takashi Iwai 26 Jul '19

26 Jul '19

The last fallback of CORB/RIRB communication error recovery is to turn on the single command mode, and this last resort usually means that something is really screwed up. Instead of a normal dev_err(), show the error more clearly with dev_WARN_ONCE() with the caller stack trace. Also, show the bus-reset fallback also as an error, too.

[alsa-devel] [PATCH 0/2] ASoC: ti: davinci-mcasp: sample format constraint fixes
by Peter Ujfalusi 26 Jul '19

26 Jul '19

Hi, The two patch fixes two issues on how the driver have placed constraints on the format size. 1. When the first stream starts and the TDM slot_width is configured we can allow formats which require less or equal number of bits on the bus. 2. For the second stream we must allow only formats which uses exact number of bits on the bus. These issues are visible around the S24_3LE, S24_LE and S32_LE formats. Regards, Peter --- Peter Ujfalusi (2): ASoC: ti: davinci-mcasp: Correct slot_width posed constraint ASoC: ti: davinci-mcasp: Support for correct symmetric sample bits sound/soc/ti/davinci-mcasp.c | 91 +++++++++++++++++++++++++++++++----- 1 file changed, 79 insertions(+), 12 deletions(-) -- Peter Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
