[alsa-devel] Need help implementing an external PCM/control plugin pair
by Dimitris Papavasiliou 20 Feb '18

20 Feb '18

Hi, I'm in the process of putting together a loudness compensation plugin for ALSA. The filtering part is implemented as an external PCM plugin and it is, more or less, ready, meaning that you can set its parameters via configuration options and it'll happily filter away in real time. I'm trying now to create a matching mixer plugin, to allow on-the-fly adjustment of the parameters, and I'm not sure what the best way of accomplishing that would be. My main concerns are: 1. I've figured out how to create a basic external control plugin, that would allow me to expose a set of controls, which the user can fiddle with, using alsamixer et al., but what would be the best way of communicating changes in the values to the PCM plugin? I could imagine using methods external to ALSA, such as a file with stored values, which the ctl plugin updates and which the PCM plugin monitors for changes, or perhaps I could try to open the mixer from inside the PCM plugin, set callbacks for each of its elements and enter a snd_mixer_wait/snd_mixer_handle_events loop, in a separate thread of course. Is there reason to prefer one way over the other? Perhaps there is a better way, I'm not aware of? 2. I'd like to support event subscription/notification, but I'm not sure how to make that work. My understanding (from searching the net and looking at ALSA's source), is that I need to provide some sort of file descriptor, which the subscribing code can poll, so as to block until there's an update. Since I have no obvious candidates for such a file, I've tried creating a pipe, handing one end to the control plugin upon initialization and then writing single bytes to the other end when there's a change in one of the controls. This works but, as far as I can see, the pipe is never actually read from, from the subscribing code, so that I would have to manually read from it somehwere, say in the read_event callback, in order to flush it. In the end, I'll probably use the descriptor from an inotify watch on the file where the plugin stores the control settings, but is this a valid approach overall? Is there some documentation specifying the exact way in which poll descriptors are handled by ALSA (in the case of an extrnal CTL plugin), that I've missed? If not, are my assumptions above (that the descriptor is only polled and that its contents are never actually read) correct? 3. Finally, and although this is not essential, I'd like to provide metadata for some controls, to support dB ranges, as that's the most natural way to set them. I see hints that this is supported for external control plugins (SND_CTL_EXT_ACCESS_TLV_READ/WRITE, the snd_ctl_ext_tlv_rw_t callback), but I'm not sure how to implement it. Is it documented somewhere? If not, could someone describe the basic approach? Thanks, Dimitris

[alsa-devel] [PATCH v4 0/2] Add support for AK5558 ADC
by Daniel Baluta 19 Feb '18

19 Feb '18

We support normal mode, TDM mode and pm. Changes since v3: [addressed Mark's comments] * use C++ comments for SPDX identifier * removed some unused widgets and controls (channel enable MUXes, TDM, DSD related stuff) * removed set_dai_mute, set_bias_level, set_dai_sysclk as they are not used. * refactored probe/remove to have symmetric operations * use snd_soc_update_bits instead of hardcode read/write operation. Changes since v2: [addressed comments from Andy, Fabio and Rob] * sort include files * use probe_new * reword the binding document * use adc@10 instead of ak5558@10 * remove file name at the beginning of codec source code. * make i2c_probe and i2c_remove parameters naming consistent. Changes since v1: [addressed comments from Andy and Fabio] * fix GPIO polarity from active high to active low for correct documentation * fix license header by using SPDX identifier * remove debug prints at the beginning of functions. * only support auto clock switching (manual switching was dead code anyway) (in the future we could add a DT property to choose between manual and auto) * Use gpiod API * use GENMASK * introduce power_off/power_on Daniel Baluta (2): ASoC: codecs: Add support for AK5558 ADC driver ASoC: ak5558: Add bindings for AK5558 ADC Documentation/devicetree/bindings/sound/ak5558.txt | 22 ++ sound/soc/codecs/Kconfig | 6 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/ak5558.c | 417 +++++++++++++++++++++ sound/soc/codecs/ak5558.h | 52 +++ 5 files changed, 499 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/ak5558.txt create mode 100644 sound/soc/codecs/ak5558.c create mode 100644 sound/soc/codecs/ak5558.h -- 2.7.4

[alsa-devel] [PATCH 0/2] ASoC: tlv320aic31xx: Optimize the master mode I2S clock handling
by Peter Ujfalusi 19 Feb '18

19 Feb '18

Hi, Instead of forcing DAC/ADC to be turned on, we can use P0 R29, Bit2 to let the I2S clocks running, but we do not want it to run all the time and we do not want I2S clocks when it is not needed (analog loopback mode). Use DAPM_SUPPLY for the bit and connect it to the in/out AIF. The DAPM routes can be modify to not include the DAC/ADC.
