Please, let me know the result of your tests. It works on Lenovo Thinkpad Carbon X1 7th gen (both analog and HDMI outputs). Okay, I will use this bug as the main tracking bug to enable the SOF driver in Fedora.Īs noted, ALSA 1.2.1+ packages (alsa-ucm-1.2.1, alsa-firmware-1.2.1) are required to get things (pulseaudio) working.

Can you reproduce this issue? If so, please provide the steps to reproduce Not with release kernels, but works well with corresponding ALSA support and 5.3/5.4 custom built kernel.Ĥ. *first* appear? Old kernels are available for download at Did it work previously in Fedora? If so, what kernel version did the issue What is the Version-Release number of the kernel:ģ. It is being developed at but is upstream in 5.3,Ģ. This support is included in the 5.3 kernel under the flag CONFIG_SND_SOC_SOF_INTEL_TOPLEVEL. ALSA 1.2.1 (in FC31 updates-testing as of yesterday) adds the firmware, topology and UCM files required to enable this in user-space, however kernel support is not enabled. For example, the Lenovo Carbon X1 Gen 7 and Yoga Gen 4 require this new firmware and kernel/ALSA support to enable directional microphone support and proper speaker configuration. Most new Intel laptops embed Xtensa or other audio DSPs now supported by the Sound Open Firmware project ().
