[PATCH] ALSA: hda/realtek: Enable mute and micmute LED on HP EliteBook 850 G7
by Kai-Heng Feng 31 Dec '20

31 Dec '20

HP EliteBook 850 G7 uses the same GPIO pins as ALC285_FIXUP_HP_GPIO_LED to enable mute and micmute LED. So apply the quirk to enable the LEDs.

[PATCH AUTOSEL 4.14 7/8] ALSA: pcm: Clear the full allocated memory at hw_params
by Sasha Levin 30 Dec '20

30 Dec '20

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit 618de0f4ef11acd8cf26902e65493d46cc20cc89 ] The PCM hw_params core function tries to clear up the PCM buffer before actually using for avoiding the information leak from the previous usages or the usage before a new allocation. It performs the memset() with runtime->dma_bytes, but this might still leave some remaining bytes untouched; namely, the PCM buffer size is aligned in page size for mmap, hence runtime->dma_bytes doesn't necessarily cover all PCM buffer pages, and the remaining bytes are exposed via mmap. This patch changes the memory clearance to cover the all buffer pages if the stream is supposed to be mmap-ready (that guarantees that the buffer size is aligned in page size).

configuring usb 2.0 audio gadget correctly via configfs?
by Bert Schiettecatte 30 Dec '20

30 Dec '20

Hi all I am using kernel 5.9 stable and I'm trying to configure the usb 2.0 audio gadget correctly so my device shows up as an audio interface when I plug it into my PC or Mac. I previously was on 4.11 and had a bunch of hacks I applied to the uac2 driver which worked fine, but a lot has changed since then and I'm wondering if by now the gadget works correctly out of the box, so I don't have to apply my hacks anymore. I'm configuring the device using configfs and that works fine, but when I plug it into my Mac I just see zero channels and the device name is capture or playback inactive. Anyway, just wanted to know what the current state of things is regarding the gadget driver and alsa. Thanks Bert
