核心 5.7 中沒有聲音設備無法載入軟體韌體

我正在使用鸚鵡作業系統（基於 Debian 不穩定）。我的音頻控制器是英特爾音頻。這是lspci：

Multimedia audio controller: Intel Corporation Device 02c8
   Flags: bus master, fast devsel, latency 32, IRQ 16, IOMMU group 11
   Memory at b629c000 (64-bit, non-prefetchable) [size=16K]
   Memory at b6000000 (64-bit, non-prefetchable) [size=1M]
   Capabilities: [50] Power Management version 3
   Capabilities: [80] Vendor Specific Information: Len=14 <?>
   Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit+
   Kernel driver in use: sof-audio-pci
   Kernel modules: snd_hda_intel, snd_sof_pci

我在 dmesg 中收到以下錯誤：

我在 alsa 和 pulseaudio 中都看不到硬體音頻設備。我已經看到了這個答案，我的問題完全相同，但是解決方案不起作用（我沒有降級核心，也不想）。手動重新載入核心模組也不起作用。sof 韌體失去但不確定如何在 Debian 中安裝它（Arch 有一個軟體包）。

您缺少 alsa-sof-firmware。

您可以按照此處的說明海報進行安裝：
