Apology for that. Changing supports_autosuspend in driver is too late for disabling autosuspend, because it was already used by USB probe routine, so it can break the balance on the following code that depends on supports_autosuspend. Fix it by using usb_disable_autosuspend() helper, and balance the suspend count in disconnect callback.

[PATCH v1 0/5] Add missing reset controls to NVIDIA Tegra ASoC drivers
by Dmitry Osipenko 04 Mar '21

04 Mar '21

Hi, This series adds missing hardware reset controls to I2S and AC97 drivers. Currently drivers happen to work properly because reset is implicitly deasserted by tegra-clk driver, but clk driver shouldn't touch the resets and we need to fix it because this breaks other Tegra drivers. Previously we fixed the resets of the AHUB and HDMI codec drivers, but turned out that we missed the I2C and AC97 drivers. Thanks to Paul Fertser for testing the pending clk patches and finding that audio got broken on Tegra20 AC100 netbook because of the missing I2S reset.

[PATCH] ALSA: usb-audio: Apply the control quirk to Plantronics headsets
by Takashi Iwai 04 Mar '21

04 Mar '21

Other Plantronics headset models seem requiring the same workaround as C320-M to add the 20ms delay for the control messages, too. Apply the workaround generically for devices with the vendor ID 0x047f. Note that the problem didn't surface before 5.11 just with luck. Since 5.11 got a big code rewrite about the stream handling, the parameter setup procedure has changed, and this seemed triggering the problem more often.

[PATCH] ASoC: SOF: Intel: hda: enable async suspend
by Ranjani Sridharan 04 Mar '21

04 Mar '21

The skylake driver disabled async suspend to prevent disabling the DSP before the card was suspended during system suspend. This code was carried over to the SOF driver. But, there is no risk of the DSP getting disabled before the card is suspended with the SOF driver. Therefore, it is safe to enable async suspend and thereby optimize the system resume time.

[PATCH] ASoC: wm8524: Do not print probe defer error
by Fabio Estevam 04 Mar '21

04 Mar '21

On an imx8mq-evk the following error is seen: [ 1.375809] wm8524-codec audio-codec: Failed to get mute line: -517 It happens because the codec driver may probe prior to the imx gpio driver, which causes a probe defer. Change to dev_err_probe() to avoid printing this error.
