In this directory, we curate linux firmware bins that for one reason or another are not ready to submit to linux-firmware (e.g., copyright owners are missing, no upstream driver/naming convention is available, etc.).
Copyright owners can contact me at antheas dot dev or open an issue (if the email fails) to have their firmware removed from this repository. The repository history will be rewritten and the files purged within 5 business days.
Awinic is a mobile audio IC company. They produce amplifiers for predominantly phones and tablets. They have a Windows driver, and an out-of-tree linux driver for mobile phones that also works in mainline Linux. This driver was submitted to the kernel in 2022, but did not get merged. Awinic has been chosen by Ayaneo for their audio amplifiers in certain devices, and from Ayn in Loki MiniPro.
However, both their Windows and Linux drivers have a big flaw: they use the same name for all firmware files, making it impossible to store firmware files for multiple devices at a time.
This is fine for their current usecase, as they distribute bespoke Windows drivers for each e.g., Ayaneo device, and one firmware file in phone ROMs. However, this raises a problem for Linux, as we can't have multiple firmware files with the same name in the same directory.
In any case, the fork of the driver that is present in Bazzite performs DMI checks to differentiate between devices, and loads the correct firmware file. This is a good solution for now and, for data preservation, we provide the bins extracted from the Windows drivers in this repository.
The currently known firmware files and their hashes are the following:
$ sha256sum awinic/*
# Ayn Loki MiniPro

# Orange Pi (?)

Bazzite has a read-only /usr/lib/firmware dir but contains symlinks, so place the files in /usr/local/firmware instead (you need to make that directory sudo mkdir -p /usr/lib/firmware). If your device is not in the list above, aw87xxx_acf.bin is provided as a fallback name.
Cirrus is good at upstreaming firmware, so this is somewhat of a staging area. Place the files in cirrus under /usr/lib/firmware/cirrus.
We said last year, but Cirrus guy slept on it. 10431fb3 is the ASUS ROG Z13 2025. 1f660105 is the Ayaneo 3.
Here are some commands to find the files:
cp *_V01_A0.bin cs35l41-dsp1-spk-prot-${SUBL}-spkid1-l0.bin
cp *_V01_A1.bin cs35l41-dsp1-spk-prot-${SUBL}-spkid1-r0.bin
cp *_V01_A0_cal.bin cs35l41-dsp1-spk-cali-${SUBL}-spkid1-l0.bin
cp *_V01_A1_cal.bin cs35l41-dsp1-spk-cali-${SUBL}-spkid1-r0.bin
# or...
cp *_V*_A01.bin cs35l41-dsp1-spk-prot-${SUBL}-spkid1.bin
cp *_V*_A01_cal.bin cs35l41-dsp1-spk-cali-${SUBL}-spkid1.binA0 is left, A1 is right, A01 is both.
ln -s cs35l41/v6.61.1/halo_cspl_RAM_revB2_29.63.1.wmfw cs35l41-dsp1-spk-cali-${SUBL}.wmfw
ln -s cs35l41/v6.61.1/halo_cspl_RAM_revB2_29.63.1.wmfw cs35l41-dsp1-spk-prot-${SUBL}.wmfw
To get SUBL:
echo 'file sound/pci/hda/* +p' | sudo tee /sys/kernel/debug/dynamic_debug/controlThen sleep resume to generate the logs in dmesg.
