[Testing - Trixie] Low microphone volumne on XPS13 9350

I'm running Testing on an XPS13 9350 (Lunar Lake) and the volume is quite low.

The output of lspci -vv is:

Code:

00:1f.3 Multimedia audio controller: Intel Corporation Lunar Lake-M HD Audio Controller (rev 10)Subsystem: Dell Device 0cc9Control: 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: 64Interrupt: pin A routed to IRQ 206IOMMU group: 18Region 0: Memory at 3015200000 (64-bit, non-prefetchable) [size=512K]Region 4: Memory at 3015000000 (64-bit, non-prefetchable) [size=2M]Capabilities: <access denied>Kernel driver in use: sof-audio-pci-intel-lnlKernel modules: snd_hda_intel, snd_sof_pci_intel_lnl
The output of inxi -A is:

Code:

Audio:  Device-1: Intel driver: intel-ipu7  Device-2: Intel Lunar Lake-M HD Audio driver: sof-audio-pci-intel-lnl  API: ALSA v: k6.12.11-amd64 status: kernel-api  Server-1: PipeWire v: 1.2.7 status: active
Looking at the output of pactl list sources I've noticed that Base Volume is set to 32%, but I was not able to find a way to increase it.

Code:

Is that the cause and how to solve it? Otherwise, where can I act to increase the mic volume?
