Hello! I’ve posted this a few weeks ago on /c/[email protected] but I didn’t get much of an answer, I hope it’s okay to post it here as well.
I use 3 audio devices on my computer: my monitor’s speakers (through HDMI), my headphones (through line-out/built-in audio) and my microphone (line-in/built-in audio). They all work fine, but when I reboot my headphones / line-out don’t seem to get recognized at all.
The only solution I’ve found thus far is to re-install alsa-utils twice after rebooting. Upon the first reinstall, my line-out / headphones reappear but my line-in mic disappears, only to come back after the second reinstall. Technically my sound works perfectly fine after this, but it feels extremely dumb to reinstall a package twice after every reboot.
Any help would be greatly appreciated, thanks in advance :)
Hm. Nothing really jumping out then. I am racking my brain trying to think of anything else to look at.
Dumb question but… Shouldn’t headphones be plugged into the headphone jack, not line out?
Headphones typically have a lower impedance than, say, an amplifier.
I’m just wondering if the audio hardware checks load impedance for audio out to prevent issues and the headphones are reading too low (tens to hundreds of ohms instead of, say, 10k-100k ohm or whatever) for a line out.
I don’t know how that explains reinstalling alsa-utils twice or thrice to fix it until the next reboot. So I guess my theory isn’t all that great.
Does it make a difference if you unplug the headphones before rebooting?
