28 Mar '25

alsa-project/alsa-lib issue #445 was opened from Asercn: # [ alsa-lib ] OpenHarmony Adaptation Proposal ## Background OpenHarmony is an open-source project incubated and operated by the OpenAtom Open Source Foundation. Its goal is to build an operating system framework and platform for intelligent terminal devices in the era of full scenarios, full connectivity, and full intelligence. ALSA, as an important audio architecture in Linux systems, allows developers to use Linux system calls in programs to control and manage the underlying operating system. Due to its efficient and easy-to-use features, it is also suitable for embedded devices, which aligns well with OpenHarmony's concept of supporting a variety of devices. Currently, ALSA is widely used in the mobile application development field of OpenHarmony. We will submit the adaptation code via a pull request (PR) as soon as possible. This issue is created to engage in in-depth discussions with the community about integrating the adaptation code. We sincerely welcome any valuable suggestions. ## Adaptation Plan 1. Details of the ALSA adaptation plan: 2. Submit back to the main community. 3. Ongoing community maintenance. ## Test Results We have completed large-scale compatibility testing, covering different versions of HarmonyOS and various types of HarmonyOS devices. The test results show that the modified version is highly compatible with the HarmonyOS system and no significant stability issues have been observed. Benefits to the Upstream Community * Can reach OpenHarmony’s large user base and developer community. * By supporting the development trends of the operating system, it ensures the long-term development potential of the project. * Enhances the project's processing capability in diverse operating environments.

[PATCH 2/3] ASoC: amd: use new ACP dev names for DAI links

[PATCH 3/3] ASoC: dwc: always enable/disable i2s irqs
by Brady Norander 26 Mar '25

26 Mar '25

Commit a42e988 ("ASoC: dwc: add DMA handshake control") changed the behavior of the driver to not enable or disable i2s irqs if using DMA. This breaks platforms such as AMD ACP. Revert to the old behavior by always enabling and disabling i2s irqs while keeping DMA handshake control.

No output when selecting S/PDIF on Asus B850-I with Realtek ALC4080
by GitHub issues - opened 26 Mar '25

26 Mar '25

alsa-project/alsa-ucm-conf issue #534 was opened from bcrescimanno: Motherobard site: https://rog.asus.com/us/motherboards/rog-strix/rog-strix-b850-i-gaming-wifi/ I get no output from the S/PDIF port on this motherboard. I'm able to workaround it using `pavucontrol` and switching the USB Audio device to the "Pro Audio" configuration and then choosing "USB Pro Audio 2" as the output device.
