I have a Lenovo T450 that plays audio over the speakers and headphones but when the headphones are used there is some white noise playing all the time as well as the audio. This white noise is not there with Windows 10 or Linux. OpenBSD recognizes the audio codec as a Realtek ALC292 but Linux and the spec sheet for my laptop say it's a Realtek ALC3232. I suspect this might be causing the error but I'm not sure how to fix it. There was no mention of an ALC3232 in /usr/src/sys/dev/pci/azalia_codec.c while there was for ALC292.
I am running a snapshot that is a few days old. Here is the output of mixerctl -av when the headphones are plugged in: inputs.dac-0:1=126,126 inputs.dac-2:3=126,126 record.adc-2:3_mute=off [ off on ] record.adc-2:3=124,124 record.adc-0:1_mute=off [ off on ] record.adc-0:1=124,124 inputs.mix_source=spkr3,mic2,beep { spkr3 mic2 beep } inputs.mix_spkr3=120,120 inputs.mix_mic2=120,120 inputs.mix_beep=120,120 inputs.mix2_source=dac-0:1,mix { dac-0:1 mix } inputs.mix3_source=dac-2:3,mix { dac-2:3 mix } inputs.mix4_source=dac-0:1,dac-2:3 { dac-0:1 dac-2:3 } inputs.mic=85,85 outputs.spkr_source=mix3 [ mix2 mix3 ] outputs.spkr_mute=on [ off on ] outputs.spkr_eapd=on [ off on ] outputs.hp_source=mix2 [ mix2 mix3 ] outputs.hp_mute=off [ off on ] outputs.hp_boost=off [ off on ] outputs.hp_eapd=on [ off on ] outputs.spkr2_source=mix2 [ mix2 mix3 ] outputs.spkr2_mute=off [ off on ] outputs.spkr2_boost=off [ off on ] outputs.spkr2_eapd=on [ off on ] inputs.spkr3=85,85 inputs.mic2=85,85 outputs.mic2_dir=input-vr80 [ none input input-vr0 input-vr50 input-vr80 input-vr100 ] record.adc-0:1_source=mic [ spkr3 mic2 beep mix mic ] record.adc-2:3_source=spkr3 [ spkr3 mic2 beep mix ] outputs.hp_sense=plugged [ unplugged plugged ] outputs.mic2_sense=plugged [ unplugged plugged ] outputs.spkr_muters=hp { hp } outputs.master=126,126 outputs.master.mute=off [ off on ] outputs.master.slaves=dac-0:1,dac-2:3,spkr,hp,spkr2 { dac-0:1 dac-2:3 spkr hp spkr2 } record.volume=124,124 record.volume.mute=off [ off on ] record.volume.slaves=adc-2:3,adc-0:1 { adc-2:3 adc-0:1 mic spkr3 mic2 } record.enable=sysctl [ off on sysctl ] Here is the dmesg: OpenBSD 7.1-current (GENERIC.MP) #580: Mon Jun 13 10:13:31 MDT 2022 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8441913344 (8050MB) avail mem = 8168697856 (7790MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xccbfd000 (66 entries) bios0: vendor LENOVO version "JBET73WW (1.37 )" date 08/14/2019 bios0: LENOVO 20BU000EUS acpi0 at bios0: ACPI 5.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SLIC ASF!
