alsa-project/alsa-lib issue #220 was opened from 0jrp0:

After a recent update to Debian, I am receiving the following error:

```shell $ amixer ALSA lib simple_none.c:1555:(simple_add1) helem (MIXER,'Mic Boost Volume',0,1,0) appears twice or more amixer: Mixer default load error: Invalid argument ```

I attempted to remove `/var/lib/alsa/asound.state`, but it didn't help. If I run `alsactl restore`, it does nothing. If I run `alsactl store`, it just dumps the duplicate Mic Boost Volume entry again.

I have an HDMI device that I don't use where this is possibly coming from. I attempted to blacklist the kernel module for `snd_hda_codec_hdmi`, but it didn't help (nor could I figure out how to persist the black list across reboots even after modifying `/etc/modprobe.d/`).

My current setup is using `pipewire` using the `pipewire-pulse` binary which connects up to `alsa`.

Some info:
