Linux sound subsystem maintainer Takashi Iwai of SUSE sent out this week's batch of sound fixes that he describes as " A collection of fixes that have been accumulated recently. The amount is still "new normal", but all small fixes. Mostly hardware-specific quirks, but including a few core fixes, too. " The "new normal" has been a common phrase recently to reflect the increased tempo of patches as well as security/bug disclosures all due to the increased pace of AI/LLM activity.

In the past it would have been viewed as a lot of fixes for this later stage of the kernel cycle, but this week's Linux 7.2-rc5 sound fixes include:

- Fixing silent streams with the Intel HDMI keep-alive silent mode. This fixes code added back in 2022 for Alder Lake and DG2/Alchemist hardware.

- A fix for detecting the internal digital microphone on the AMD-powered MSI Vector A16 HX A8WIG laptop.

- Adding some new Sound Open Firmware quirks for new Dell XPS Wildcat Lake and Dell XPS Panther Lake models to enable the sidecar amp configuration.

- The HP ZBook 8 G2a laptop needs an inverted LED quirk handling for opposite speaker mute LED polarity.

- A fixed rate quirk for the JBL Quantum650 Wireless headset.

- More pop noise quirks for the Dell Pro QC1255.

- A qurik for the HP EliteBook 830 G8 (8AB8) to enable the mute LED.

- Fixing speakers on the Lunnen Ground 14.

- Fixing speakers on the Alienware x16 R2.

- Fixing some ASUS TUF ACP70-based systems like the TUF Gaming Vivobook 18 and TUF Gaming A14 FA401EA so the SoundWire driver is properly loaded on those platforms.

- A quirk for the HP Pavilion x360 to deal with silent output.

Lots of quirks this week! The full list of patches can be found via this pull request .
