[alsa-devel] [PATCH 0/2] ALSA: usb-audio: UAC2 effect unit parsing
by Takashi Iwai 17 Feb '20

17 Feb '20

Hi, UAC2 Effect Unit needs different parsing from Processing Unit and co, and this patch set implements the partial support for that. As it's the fix on top of the latest USB-audio fix, I'd like to apply through sound git tree. So please review and ack if USB header change is OK. thanks, Takashi === Takashi Iwai (2): usb: audio-v2: Add uac2_effect_unit_descriptor definition ALSA: usb-audio: Parse source ID of UAC2 effect unit include/linux/usb/audio-v2.h | 12 ++++++++++++ sound/usb/mixer.c | 6 ++++++ 2 files changed, 18 insertions(+) -- 2.16.4

[alsa-devel] DMARC & gmail & cirrus.com
by Jaroslav Kysela 17 Feb '20

17 Feb '20

Hi all, today, all gmail users were unsubscribed from the mailing list, because we have users who sends e-mails from domains with the DMARC policy reject (like cirrus.com). The mailman counts those bounces and unsubscribe users who do not receive those e-mails. The nice explanation is here: https://www.linuxchix.org/content/mailing-list-changes I can enable the "Replace the From: header address" in the mailman config to "Munge From" like in the above example, but it will mean that From: will be altered (see the explanation). Another option is to disable the bounce check in mailman, but it will cause that the "dead" subscribers are not detected anymore. Any opinions on this?

[alsa-devel] [PATCH] drm/mediatek: fix race condition for HDMI jack status reporting
by Tzung-Bi Shih 17 Feb '20

17 Feb '20

hdmi_conn_detect and mtk_hdmi_audio_hook_plugged_cb would be called by different threads. Imaging the following calling sequence: Thread A Thread B -------------------------------------------------------------------- mtk_hdmi_audio_hook_plugged_cb() mtk_cec_hpd_high() -> disconnected hdmi_conn_detect() mtk_cec_hpd_high() -> connected plugged_cb(connected) plugged_cb(disconnected) The latest disconnected is false reported. Makes mtk_cec_hpd_high and plugged_cb atomic to fix. plugged_cb and codec_dev are also in danger of race condition. Instead of using mutex to protect them: - Checks NULLs first. - Uses WRITE_ONCE() to prevent store tearing (i.e. write to plugged_cb after codec_dev). - Uses codec_dev as a signal to report HDMI jack status.

[alsa-devel] [PATCH v2 0/3] simple-audio-card codec2codec support
by Samuel Holland 17 Feb '20

17 Feb '20

We are currently using simple-audio-card on the Allwinner A64 SoC. The digital audio codec there (sun8i-codec) has 3 AIFs, one each for the CPU, the modem, and Bluetooth. Adding support for the secondary AIFs requires adding codec2codec DAI links. Since the modem and bt-sco codec DAI drivers only have one set of possible PCM parameters (namely, 8kHz mono S16LE), there's no real need for a machine driver to specify the DAI link configuration. The parameters for these "simple" DAI links can be chosen automatically. This series adds codec2codec DAI link support to simple-audio-card. Codec to codec links are automatically detected when DAIs in the link belong to codec components. I tried to reuse as much code as possible, so the first two patches refactor a couple of helper functions to be more generic. The last patch adds the new feature and its documentation.

The ALSA support for Apogee Duet FireWire starts at Linux kernel v4.21. As you can see, the support is just for packet streaming, thus it's just possible to transmit/receive PCM frames and MIDI messages. However, the device is designed to run just depending on its internal clock (e.g. 47994 frames/sec), thus at present it generates periodical noise since the ALSA driver is designed to transmit just the same number of PCM frames as sampling rate (e.g. 48000 frames/sec). The support of any control is expected to be implemented in userspace application. This is the reason that you can see no elements in ALSA control application (e.g. alsamixer). However, the protocol to control the device is not clear yet. As long as I know, it's complicated and requires the batch of codes for the application. This is the reason that ALSA in-kernel driver doesn't have the code. Regards Takashi Sakamoto

[alsa-devel] Best way to interface with equalizer
by Manusha Wijekoon 16 Feb '20

16 Feb '20

Hello I want to control ALSA equalizer from a mobile phone GUI. Essentially I would like to build a small GUI that runs on a phone to allow a user to change equalizer visually. I want this to be very smooth and stable. Few options that I can think of are: 1. Have an agent program running in the linux machine which controls alsa by sending various commands through linux shell. 2. Agent program running in the linux machine directly interfaces to ALSA through its C interface. 3. Is there a control interface provided by ALSA, for example REST like service? 3 seem to be the best option as it involves less work. 1 looks fragile to me. What are your recommendations? Thank you S

[alsa-devel] [PATCH v3] ALSA: usb-audio: Add support for Presonus Studio 1810c
by mickflemm＠gmail.com 15 Feb '20

15 Feb '20

From: Nick Kossifidis <mickflemm(a)gmail.com> This patch adds support for Presonus Studio 1810c, a usb interface that's UAC2 compliant with a few quirks and a few extra hw-specific controls. I've tested all 3 altsettings and the added switch controls and they work as expected. More infos on the card: https://www.presonus.com/products/Studio-1810c Note that this work is based on packet inspection with usbmon. I just wanted to get this card to work for using it on our open-source radio station: https://github.com/UoC-Radio v2 address issues reported by Takashi: * Properly get/set enum type controls * Prevent race condition on switch_get/set * Various control naming changes * Various coding style fixes v3 improve readability of sample rate filtering and some other minor changes.
