Linux 7.3 sees significant audio hardware support updates, enhancing compatibility with AMD, Qualcomm, and Realtek components. Engineers should explore new driver integrations for next-gen devices.
The upcoming Linux 7.3 kernel is set to expand its audio capabilities with a slew of new hardware support, as submitted by sound subsystem maintainer Takashi Iwai of SUSE. This update is crucial for engineers working with diverse audio hardware, ranging from AMD to Qualcomm components, as it promises to enhance compatibility and performance across various systems.
Among the notable additions, Linux 7.3 supports the AMD ACP7.B/ACP7.F, which is particularly relevant for next-gen Ryzen laptops. This builds on the existing AMD ACP Sound Open Firmware infrastructure, ensuring a seamless transition for engineers familiar with previous iterations. The kernel also introduces support for Cirrus Logic CS35L62, Loongson 2K0300, Meson GX, Qualcomm LPI MI2S, and Realtek RT1321 VA1/2 and RT766/7, broadening the scope of supported devices.
Phoronix highlights the inclusion of AW88399 HD-audio side codec support, which is a boon for users of newer Lenovo Legion gaming laptops. Additionally, support for Hygon and Lisuan HDMI controllers is now available, alongside various quirks and fixes for Realtek and Conexant codecs found in ASUS, Lenovo, and Acer laptops. These updates are expected to improve audio handling and reduce issues related to codec compatibility.
On the professional audio front, USB audio support now includes the Pioneer DJ DJM-S11, a high-end DJ mixer retailing at approximately $2269 USD. This addition is a nod to the growing intersection of professional audio equipment and Linux systems.
For engineers, the practical impact is clear, Linux 7.3's sound subsystem updates offer improved hardware compatibility and enhanced functionality, making it an essential upgrade for those managing diverse audio environments. As the merge window for Linux 7.3 remains open, further optimizations and integrations are anticipated, potentially making this release one of the most performance-focused in recent memory.
