[PATCH AUTOSEL 5.11 34/67] ALSA: usb-audio: Add support for Pioneer DJM-750
by Sasha Levin 24 Feb '21

24 Feb '21

From: Olivia Mackintosh <livvy(a)base.nu> [ Upstream commit b952ac76a20bc0b23cd7e22de19fb407713238a3 ] This adds the Pioneer DJ DJM-750 to the quirks table and ensures skip_pioneer_sync_ep() is (also) called: this device uses the vendor ID of 0x08e4 (I'm not sure why they use multiple vendor IDs but many just like to be awkward it seems). Playback on all 8 channels works. I'll likely keep this working in the future and submit futher patches and improvements as necessary.

[PATCH AUTOSEL 5.11 33/67] ASoC: Intel: bytcr_rt5640: Add new BYT_RT5640_NO_SPEAKERS quirk-flag

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit 1851ccf9e155b2a6f6cca1a7bd49325f5efbd5d2 ] Some devices, like mini PCs/media/top-set boxes do not have any speakers at all, an example of the is the Mele PCG03 Mini PC. Add a new BYT_RT5640_NO_SPEAKERS quirk-flag which when sets does not add speaker routes and modifies the components and the (optional) long_name strings to reflect that there are no speakers.

[PATCH alsa-lib 1/3] mixer: Unify simple_none: base_len() exception handling
by Hans de Goede 24 Feb '21

24 Feb '21

Unify simple_none: base_len() exception handling: 1. In the "Input Source" and "3D Control" cases the base-name is the same as the full-name and base_len() simply returns strlen(name). Instead of returning 0 when the type is unknown, set the type to CTL_SINGLE and return strlen(name). This allows removing the special case for base_len() returning 0 in simple_event_add(). 2. Move the special handling for "Capture Volume" and "Capture Switch" from simple_event_add() to base_len(), so that we handle all exceptions inside base_len(). Instead of handling some special cases in base_len() and other special cases in simple_event_add().

[PATCH v2] leds: trigger: audio: Add an activate callback to ensure the initial brightness is set
by Hans de Goede 24 Feb '21

24 Feb '21

Some 2-in-1s with a detachable (USB) keyboard(dock) have mute-LEDs in the speaker- and/or mic-mute keys on the keyboard. Examples of this are the Lenovo Thinkpad10 tablet (with its USB kbd-dock) and the HP x2 10 series. The detachable nature of these keyboards means that the keyboard and thus the mute LEDs may show up after the user (or userspace restoring old mixer settings) has muted the speaker and/or mic. Current LED-class devices with a default_trigger of "audio-mute" or "audio-micmute" initialize the brightness member of led_classdev with ledtrig_audio_get() before registering the LED. This makes the software state after attaching the keyboard match the actual audio mute state, e.g. cat /sys/class/leds/foo/brightness will show the right value. But before this commit nothing was actually calling the led_classdev's brightness_set[_blocking] callback so the value returned by ledtrig_audio_get() was never actually being sent to the hw, leading to the mute LEDs staying in their default power-on state, after attaching the keyboard, even if ledtrig_audio_get() returned a different state. This could be fixed by having the individual LED drivers call brightness_set[_blocking] themselves after registering the LED, but this really is something which should be done by a led-trigger activate callback. Add an activate callback for this, fixing the issue of the mute LEDs being out of sync after (re)attaching the keyboard.

One might check twice (or more) if it's not certain, too. That is, check the jack immediately, and if the jack state really changed, report it so. OTOH, if the jack state doesn't change from the old state, it can retry after some delay. thanks, Takashi
