Hi all,

I am looking for the soundwire device drivers which run on x86 CPU for PC based platforms.

linux/drivers/soundwire at master · torvalds/linux · GitHub

Can the above mentioned mainline tree drivers can be used for this purpose?

config SOUNDWIRE_INTEL depends on ACPI && SND_SOC

config SOUNDWIRE_QCOM depends on SND_SOC

As per the Kconfig file, both the Intel and Qualcomm SoundWire Master driver depend on SND_SOC, does it mean it is only possible to run on SoC CPU(Arm chipsets)?

Here's what you need in your .config to use SoundWire on x86-based hardware. Today this includes mostly Dell platforms, HP x360 convertible laptops and Intel 'bishop canyon' NUC laptops.
