[alsa-devel] [PATCH v2 1/3] dell-led: Change dell-led.h to dell-common.h
by Kai-Heng Feng 07 Apr '18

07 Apr '18

[alsa-devel] [PATCHv5 0/5] Motorola Droid 4 Audio Support
by Sebastian Reichel 03 Apr '18

03 Apr '18

Hi, This adds audio support to Motorola Droid 4. I dropped the regulator from the DT binding as requested by Mark. Tested: - Playing via both DACs using Speaker, Earpiece, Headphone - Recording using internal Mic - Volume Controls Known not to work: - 3.5mm detection support (requires closed source firmware, needs further investigation) - Modem / Bluetooth Audio (this needs something more sophisticated than the audio-graph-card driver. I will have a look once the basic support has been merged) Changes since PATCHv4: * Replace verbose GPL text with SPDX header * Use "GPL v2" as MODULE_LICENSE * Drop "default MFD_CPCAP" for the codec driver * Use SOC_SINGLE instead of SOC_ENUM for Phase invert switches * Find DT node by node name instead of by compatible property - Drop Acked-by from Rob Herring * Add new patch for MFD driver to implement the mentioned DT change Changes since PATCHv3: * Drop regulator from DT binding, request VAUDIO from global regulator namespace instead Changes since PATCHv2: * Fix a whitespace issue * Fix const notes Takashi provided * Fix a DAPM route issue I accidently introduced in v2 Changes since PATCHv1: * Add patch from Tony exporting soc_dpcm_runtime_update * Integrate DT patch for vaudio initial mode * Split dt-binding from codec patch and add Ack from Rob * Fix CPCAP position in Kconfig/Makefile * Avoid "err +=" constructs * Simplify reset function * Drop cpcap_audio_read/write helpers * Do not use tertiary operator for mute register value * Update Input Mux logic * Switch from simple-audio-card to audio-graph-card -- Sebastian Sebastian Reichel (5): dt-bindings: mfd: motorola-cpcap: document audio-codec ASoC: codec: cpcap: new codec mfd: motorola-cpcap: Add audio-codec support ARM: dts: motorola-cpcap-mapphone: add audio-codec ARM: dts: omap4-droid4: add soundcard .../devicetree/bindings/mfd/motorola-cpcap.txt | 42 + arch/arm/boot/dts/motorola-cpcap-mapphone.dtsi | 13 + arch/arm/boot/dts/omap4-droid4-xt894.dts | 78 + drivers/mfd/motorola-cpcap.c | 51 +- sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/cpcap.c | 1568 ++++++++++++++++++++ 7 files changed, 1757 insertions(+), 1 deletion(-) create mode 100644 sound/soc/codecs/cpcap.c -- 2.16.1

[alsa-devel] [PATCH 0/8] Enablement of BT I2S controller instance for AMD APUs
by Vijendar Mukunda 01 Apr '18

01 Apr '18

This patch set updates Audio CoProcessor (ACP) audio drivers to enable BT I2S controller instance. In Audio Coprocessor, There are three I2S controllers can be configured/enabled.(I2S SP, I2S MICSP, BT I2S) Default enabled I2S controller instance is I2S SP instance. There is a requirement to enable BT I2S controller Instance along with I2S SP controller instance. This patch set bring up functionality to render & capture on BT I2S controller instance. The current patch set also includes a new dependent patch. The current code is based on asoc-next, but I'm happy to rebase on whatever tree this ends up going through if there are any problems applying. Vijendar Mukunda (8): ASoC: dwc: I2S Controller instance param added ASoC: amd: dma driver changes for BT I2S controller instance ASoC: amd: dma descriptor changes for BT I2S Instance ASoC: amd: Interrupt handler changes for BT I2S instance ASoC: amd: prepare callback modifications for bt i2s instance ASoC: amd: pointer and trigger callback modifications for bt i2s ASoC: amd: 16bit resolution support for bt i2s instance ASoC: amd: enabling bt i2s config after acp reset include/sound/designware_i2s.h | 6 + sound/soc/amd/acp-pcm-dma.c | 531 +++++++++++++++++++++++++++++++++-------- sound/soc/amd/acp.h | 50 +++- sound/soc/dwc/dwc-i2s.c | 1 + sound/soc/dwc/local.h | 1 + 5 files changed, 481 insertions(+), 108 deletions(-) -- 2.7.4

[alsa-devel] [PATCH v4] ASoC: AMD: Enable/Disable auxiliary clock via common clock framework

This enables/disables and sets auxiliary clock at 25Mhz. It uses common clock framework for proper ref counting. This approach will save power in comparison to keeping it always On in firmware.

[alsa-devel] Regression? No sound with HDMI audio (snd-hda-intel) with kernel 4.15(.*)
by VDR User 30 Mar '18

30 Mar '18

Hi, I upgraded my Debian Sid box from kernel 4.14.31 to 4.15.14 and I no longer get sound over HDMI with my Nividia GT430. Nvidia driver version is 390.48. Neither the Nvidia installer nor dkms makes any difference. My alsa-utils is 1.1.3-1 and my ~/.asoundrc is: ~$ cat .asoundrc pcm.!default "hdmi:NVidia,1" ~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 I'm using 'speaker-test -c 2 -t wav -Dhw:CARD=1,7' for testing. After kernel 4.15.14 didn't work, I compiled kernel 4.15 and still got no audio. I then compiled kernel 4.15-rc9 and audio worked. From there I tried to bisect the exact patch that broke the audio but got the following: ~$ cd /usr/src /usr/src$ git clone https://github.com/torvalds/linux.git /usr/src$ cd linux /usr/src/linux$ git bisect start -- sound/hda sound/pci/hda /usr/src/linux$ git bisect good v4.15-rc9 /usr/src/linux$ git bisect bad v4.15 No testable commit found. Maybe you started with bad path parameters? /usr/src/linux$ I'm not sure what went wrong there, hopefully one of you reading this may have an idea. It's worth noting I upgraded another near-identical system and HDMI audio is working fine with 4.15.* on that box. That box has an Nvidia GT520 but other than that the package versions, driver version, etc. are all the same. Also, it's connected to a surround receiver whereas the non-working box is connected directly to a tv. Please let me know if any other info is needed or what I can do/try to debug this further. Any help is greatly appreciated! -Derek
