Hi, i need a little help getting my internal mic to show up on a Acer A315-24PT laptop. The Acer wiki article doesn't list this model. Out of the box the speakers and headphone jack work but the internal mic doesn't. Alsamixer lists the card as "HD Audio generic" and the chip as "Realtek ALC255". There are no input devices available in alsamixer, it says "This sound devie does not have any capture controls". In Pavucontrol, the card shows up differently, as a "Family 17h/19h HD Audio controller Analog input". If I open any program that needs to use the mic, I can select that Analog Input, but sound never registers. During boot I searched for snd and got the following:
[ 5.505476] snd_pci_acp6x 0000:03:00.5: enabling device (0000 -> 0002)
[ 5.591755] snd_hda_intel 0000:03:00.1: enabling device (0000 -> 0002)
[ 5.591882] snd_hda_intel 0000:03:00.1: Handle vga_switcheroo audio client
[ 5.592278] snd_hda_intel 0000:03:00.6: enabling device (0000 -> 0002)

[ 5.641095] snd_hda_codec_realtek hdaudioC1D0: autoconfig for ALC255: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker
[ 5.641111] snd_hda_codec_realtek hdaudioC1D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
[ 5.641114] snd_hda_codec_realtek hdaudioC1D0: hp_outs=1 (0x21/0x0/0x0/0x0/0x0)
[ 5.641117] snd_hda_codec_realtek hdaudioC1D0: mono: mono_out=0x0
[ 5.641119] snd_hda_codec_realtek hdaudioC1D0: inputs:Seems like it doesn't see any inputs.....
Things I have tried:
-Install sof-firmware since one of the Acer articles says it works better (made no difference AFAICT)
-Add "snd_rn_pci_acp3x.dmic_acpi_check" as a boot paramter (made no difference).
-Blacklisted the "snd_hda_intel" driver that one of the articles suggested (this killed audio entirely, there were no messsages related to snd at all on boot and no output or input devices available).
Kind of at a loss, any ideas? Of course the mic works fine in Windows.....
