 Posted: Tue Oct 26, 2021 6:15 pm Post subject: alsa: amixer alsamixer now requires arguments... [solved] |
 |
|
Had not problem with alsa for years now.
Currently, both amixer and alsamixer commands fail. | Code: | user@amd64 ~ $ amixer
amixer: Mixer attach default error: L'hôte cible est arrêté ou en panne
user@amd64 ~ $ alsamixer
cannot open mixer: L'hôte cible est arrêté ou en panne |
As a side note: Did the libxcrypt switch before such issues.

So your physical interface seems to be card 0, device 0, right?
Do amixer and alsmixer work if you (temporarily) rename your .asoundrc? |

First time I have to provide parameters to the command...
I'd wish I could put things back as they were...

Wait! We're not done yet! 
If you start alsamixer with "-c0", alsamixer will attach directly to card 0, your physical interface. I'm glad it works, because it means that ALSA works.
If you start alsamixer without "-c0", it will attach to the default device, which is by default also card 0. But in your .asoundrc, you define a different default device:
| Code: | # default device
pcm.!default {
type plug
slave.pcm "aloopDuplex"
} |
And this device doesn't work.
It looks like many entries in your .soundrc are related to Jack. Do you use Jack? Do you want it? If not, it's probably best to remove your .asoundrc.
If you want to use Jack, you should try to find out what's wrong there. I'm afraid I won't be able to help you, because I don't know anything about Jack. |

Yes, using jack as main sound stack, with alsa entry and output.
apulse here, instead of pulseaudio...
I've always found .asoundrc not understandable...
Guess I'll have to dive into that one day...

Hi, I don't know exactly how that error message comes from using loopback for pcm, but you can force the default device for mixer control with a line in ~/.asoundrc: | Code: | | ctl.!default { type hw; card PCH; } |
where PCH is the very beginning of a card description in aplay -l, also the bracketed [ ID ] in that part of /proc/asound/cards. |

adding some information since I had the same issue
mine came from removing pulseaudio and pipewire[server] from my system (really don't get why theses project still exist, as long as I remember I never had issue with alsa.... not same with these 2... cpu usage, lags, glitches... but I thought that pulse was mandatory now since I saw it on every recent distrib....)
be sure to clean the /etc/alsa/conf.d from remaining conf (pulse or pipewire), this solved the issue on my side |
