x1carbon gen 9 (tiger lake) all capture devices at max volume (mic boost, capture, dmic0 front, dmic0 rear, dmic1 2nd front, dmic1 2nd rear, PGA2.0 2 M) still reads from mic is ~5-7% (as can be seen in `arecord -vv --format=dat /dev/null` )

device is using sof-audio-pci-intel-tgl: ``` $ sudo lspci -vvv -s 00:1f.3 00:1f.3 Audio device: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20) (prog-if 80) Subsystem: Lenovo Device 22d5 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 64 Interrupt: pin A routed to IRQ 185 IOMMU group: 13 Region 0: Memory at 603d1c8000 (64-bit, non-prefetchable) [size=16K] Region 4: Memory at 603d000000 (64-bit, non-prefetchable) [size=1M] Capabilities: [50] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] Vendor Specific Information: Len=14 <?> Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee00998 Data: 0000 Kernel driver in use: sof-audio-pci-intel-tgl Kernel modules: snd_hda_intel, snd_sof_pci_intel_tgl
