[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] [PATCH] ASoC: pxa: remove incorrect do_div() call
by Arnd Bergmann 26 Feb '16

26 Feb '16

The new optimized do_div implementation (now in asm-generic/next) exposes a glitch in the brownstone audio driver by producing a compile-time warning: sound/soc/pxa/brownstone.c: In function 'brownstone_wm8994_hw_params': sound/soc/pxa/brownstone.c:67:85: warning: comparison of distinct pointer types lacks a cast sound/soc/pxa/brownstone.c:67:10125: warning: right shift count >= width of type [-Wshift-count-overflow] sound/soc/pxa/brownstone.c:67:10254: warning: passing argument 1 of '__div64_32' from incompatible pointer type [-Wincompatible-pointer-types] The driver just divides two plain integer values, so it should not use do_div to start with, but has apparently done so ever since the code was first merged. This replaces do_div with a simple division operator. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> --- I think this one is harmless, so we only need it in 4.5 to avoid the warning, but not backported to earlier kernels.

[alsa-devel] [PATCH 3/3] ASoC: fsl_ssi: remove register defaults
by Maciej S. Szmigiero 22 Feb '16

22 Feb '16

There is no guarantee that on fsl_ssi module load SSI registers will have their power-on-reset values. In fact, if the driver is reloaded the values in registers will be whatever they were set to previously. This fixes hard lockup on fsl_ssi module reload, at least in AC'97 mode.

[alsa-devel] [PATCH v2 00/14] ASoC: hdac_hdmi: Add DP & notification support
by Subhransu S. Prusty 15 Feb '16

15 Feb '16

This patch series adds DP audio and hotplug notification support. On Skylake two DP ports are available and to enable DP on both ports all pins need to be enabled. There is a special vendor widget which need to be programmed to enable all pins and converters. This series adds hotplug notification, read/set constraint based on ELD, enable all pin/cvts, DP1.2, programs the audio infoframe for DP. There is a one to one mapping between converter and stream, so the dais are created based on the no of streams supported on hdmi codec. Even though cvts can be mapped dynamically to the streams, currently it is statically mapped as simultaneous playback on both DP and HDMI is not supported as of now. Pin muxes and controls are created dynamically to map converter to pin widget. So at run time specific pin is mapped to the dai based on the control selected (based on the display type DP/HDMI connected). Finally the DP audio infoframe programming is added to support the DP feature. Also with hotplug notification support, ELD is read and capabilities are set for rate, formats and channels. drm_eld sound/core framework is updated to limit the formats based on ELD. There are few fixes one fixing the static checker warning and other one not to fail if no connection list is found for a pin widget. Pls note, the 11th patch is adding a small macro for getting connection type in drm header, we have CCed drm folks on that and this one. Pls ack so that we can have this series merged thru sound trees changes in v2: - Address review comments - Dropped devm_xxx for cvt and pin memory allocation. - Dropped the ELD helper APIs from core and copied to driver. - Updated notification patch to add PM fixes from legacy hda. - commit message and change log updated for display power fix. - Updated DRM helper APIs and the caller Jeeja KP (1): ASoC: hdac_hdmi: Add codec suspend/resume handler Ramesh Babu (1): ASoC: hdac_hdmi: Fix to keep display active while enumerating codec Subhransu S.

[alsa-devel] Usb audio - unsuported sampling rates
by Gordon Dilan 12 Feb '16

Hello, I'm using an usb mic which(according to it's producer should support up to 48kHz sampling rate). The problem is ALSA allows me to use only 16 kHz for this device. I do not want to resample the data, I want to sample it at 48kHz in order to be able to record some high pitch sounds 18-20kHz. I would want to try to do any modifications necessary in order to try support 48kHz, but I'm not sure where to start.

[alsa-devel] [PATCH] ASoC: cs42xx8: fix the noise in the right dac channel when playback mono wav with record in background
by Zidan Wang 04 Feb '16

04 Feb '16

When playback mono wav with record in background, there will be some nosie in the right dac channel. It seems that the ADC data has been routed to the dac channel. The cs42888 have 8 dac channels, it's appropriate to mute the unused dac channels, and the noise will disappear.

[alsa-devel] [PATCH v2 1/3] ARM: shmobile: armadillo800eva: Properly specify HDMI audio link format
by Lars-Peter Clausen 29 Jan '16

29 Jan '16

The DAI link format should be specified for the whole link rather than just one component on the link. So move the format specification for the HDMI audio link from the CPU component to the link itself. Since the sh-mobile-hdmi DAI driver doesn't implement the set_fmt() callback in this case there is no functional difference between only specifying the the format for the CPU side or for the whole link, but the later it will allow us to remove support for just specifying the format for one component.
