[alsa-devel] Trouble about Roland UA-11 UA-33 UA-55 and snd-usb-audio module
by FirebUntU 07 Mar '16

07 Mar '16

Hi guys, I write you about support of snd-usb-audio module and a relatively-new gamma of devices from Roland/Edirol: DUO CAPTURE, TRI CAPTURE and QUAD CAPTURE respectively: UA-11, UA-33, UA-55 These aren't not listed in the Alsa db. I have searched a solution for a week and I haven't found a trick to make UA-11 to work under Alsa 1.25.0 then I downloaded the driver for try to patch it and I found these devices is not listed in the tricks table In despair I have played with the switch button called "EXT * **" in the bottom of the unit of UA-11 and magically the device ID is transformed from * 0582:012b to ** 0582:0137 Image: https://dl.dropbox.com/u/32759898/output.jpg (Rear of the UA-11 unit, from the manual) *Before* (Recognized from udev - Unknown from alsa): http://www.alsa-project.org/db/?f=502ee68cf31882ba9ef23525fd66452c34d329e1 *After* (Recognized from udev - Recognized from alsa): http://www.alsa-project.org/db/?f=b2ae3e4331fb3fe613ba71e7aba1ad2e0e6dcd29 In the tricks table header of ALSA the 0582:0137 stay for PM-1000 in /TODO/ statement. I understand the EXT switch, undiscovered in the manual of the DUO CAPTURE is - as the fact - the Advanced Mode. Now the peripherical running both in playback and recording in 16 and 24 bit and without any mixer options in alsamixer. Can you update future releases with this gamma of devices? Awaiting for your positive response :) Thanks. Best regards, Leonardo

[alsa-devel] [PATCH 1/2] ASoC: cs35l32: avoid uninitialized variable access
by Arnd Bergmann 06 Mar '16

06 Mar '16

gcc warns about the possibilty of accessing a property read from devicetree in cs35l32_i2c_probe() when it has not been initialized because CONFIG_OF is disabled: sound/soc/codecs/cs35l32.c: In function 'cs35l32_i2c_probe': sound/soc/codecs/cs35l32.c:278:2: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized] The code is actually correct because it checks the dev->of_node variable first and we know this is NULL here, but by adding a check for IS_ENABLED(CONFIG_OF), we can let the compiler know as well, and also generate smaller object code.

[alsa-devel] [RFC v2 0/6] ASoC: Add mediatek HDMI codec support
by Philipp Zabel 05 Mar '16

05 Mar '16

Hi, this time we add an interface for Jyri's generic hdmi-codec driver [1] to the mediatek hdmi bridge driver. In place of a separate machine driver, the existing mt8173-rt5650-rt5676 driver is extended to link to the hdmi-codec instance provided by the hdmi bridge driver. The alsa jack support, previously implemented by the custom mediatek hdmi codec and machine drivers, is bolted on top of hdmi-codec using Russell's HDMI notifier prototype. It's all still a bit rough, but I could use some feedback at this point. Have we achieved consensus to go forward with the hdmi-codec approach? Is it ok to use an alsa jack for HDMI HPD status reporting? The mediatek drm patches apply on top of https://patchwork.kernel.org/patch/7949021/ ("drm/mediatek: Add HDMI support") the asoc patches depend on these two patches: https://patchwork.kernel.org/patch/7215121/ ("ALSA: pcm: add IEC958 channel status helper for hw_params") [1] https://patchwork.kernel.org/patch/7215271/ ("ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders") best regards Philipp Koro Chen (1): ASoC: mediatek: Add HDMI dai-links in the machine driver Philipp Zabel (5): drm/mediatek: hdmi: Add audio interface to the hdmi-codec driver ASoC: mediatek: address dai link array entries by enum video: rmk's HDMI notification prototype drm/mediatek: hdmi: issue notifications ASoC: hdmi-codec: Use HDMI notifications to add jack support .../bindings/sound/mt8173-rt5650-rt5676.txt | 5 +- drivers/gpu/drm/mediatek/Kconfig | 1 + drivers/gpu/drm/mediatek/mtk_cec.c | 5 + drivers/gpu/drm/mediatek/mtk_drm_hdmi_drv.c | 192 +++++++++++++++++++++ drivers/gpu/drm/mediatek/mtk_hdmi.c | 26 +++ drivers/gpu/drm/mediatek/mtk_hdmi.h | 4 + drivers/video/Makefile | 2 +- drivers/video/hdmi-not.c | 61 +++++++ include/linux/hdmi-not.h | 39 +++++ include/sound/hdmi-codec.h | 6 + sound/soc/codecs/hdmi-codec.c | 72 +++++++- sound/soc/mediatek/mt8173-rt5650-rt5676.c | 66 ++++++- 12 files changed, 470 insertions(+), 9 deletions(-) create mode 100644 drivers/video/hdmi-not.c create mode 100644 include/linux/hdmi-not.h -- 2.6.2

[alsa-devel] [PATCH 0/4] Fix headphone detection on Acer Chromebook 13
by Jonathan Tinkham 04 Mar '16

04 Mar '16

Headphone output works, but headphone detection does not. The problem is improper inversion of the jack gpio, and improper naming of the DAPM switch. With these changes, headphone insertion and removal is picked up by userspace, and the switch properly toggled.

[alsa-devel] writing an alsa driver
by Michele Curti 04 Mar '16

04 Mar '16

Hi all, I'm going to *try* to "write" a driver for the sound card on my new laptop, an asus x205ta. To be fair I have almost no experience but I'm hoping that all the code is already present and it only needs some adaptations. The cpu is a intel bay trail z3735f, the sound card is a realtek rt5648 that has the same product Id of the rt5645 (0x6308). I see in kernel sources: - the codec driver sound/soc/codecs/rt5645.c - a baytrail board that uses the rt5640 sound/soc/intel/boards/byt-rt5640.c - a braswell board that uses the rt5645 sound/soc/intel/boards/cht_bsw_rt5645.c What do you think? Is it feasible, given a good amount of free-time? :p Thanks, Michele

[alsa-devel] Creative ca0132 on Gigabyte Z170X Gaming 7 motherboard: no sound
by Scott Doty 04 Mar '16

04 Mar '16

Hello, Didn't see a response on alsa-user, so thought I'd better roll up my sleeves and get to work. :) The ca0132 codec seems to do everything on my Gigabyte Z170X Gaming 7 motherboard but make sound. I can see the mixer settings, change them, even see the DSP settings -- but no sound out, either with HP or SPDIF. http://www.alsa-project.org/db/?f=6373811de293125e4e8c345c0c2d4a736c1fc2b8 I do see this in the startup messages: [ 9.314893] snd_hda_intel 0000:01:00.1: Handle vga_switcheroo audio client [ 9.321116] snd_hda_intel 0000:00:1f.3: failed to add i915 component master (-19) I've tried all the fixes I could find reference to, as well as using iecset, but no joy. I also tried editing the driver to disable the "vga_switcheroo" flag, but that didn't work either. (Which is too bad, I thought that would be a quick fix that I could report. :/ ) If someone could point me in the right direction, I think I can investigate this and get it working. Any assistance greatly appreciated. Thanks, -Scott

[alsa-devel] [PATCH v2] ASoC: cht_bsw_rt5645: Fix writing to string literal
by Carlo Caione 03 Mar '16

03 Mar '16

From: Carlo Caione <carlo(a)endlessm.com> We cannot use strcpy() to write to a const char * location. This is causing a 'BUG: unable to handle kernel paging request' error at boot when using the cht-bsw-rt5645 driver. With this patch we also fix a wrong indexing in the driver where the codec_name of the wrong dai_link is being overwritten.
