Realtek driver installation gone wrong, audio and microphone stopped working |

Trending 3 months ago

[Ubuntu 22.04.4 LTS] I messed up. I tried fixing nan rumor immoderate ubuntu users look to have, namely that nan sound measurement is measurement little than connected windows (even pinch over-amplification enabled). I wanted to instal Realtek driver to spot if it would activity better. I followed nan instructions, sewage an error, it didn't work. But aft a reboot I recovered myself successful a position that's worse.

  1. Speakers and microphone don't work. All I get is 'Dummy output'.
  2. alsamixer doesn't work. The terminal output is this:
ALSA lib confmisc.c:855:(parse_card) cannot find paper '0' ALSA lib conf.c:5178:(_snd_config_evaluate) usability snd_func_card_inum returned error: No specified record aliases directory ALSA lib confmisc.c:422:(snd_func_concat) correction evaluating strings ALSA lib conf.c:5178:(_snd_config_evaluate) usability snd_func_concat returned error: No specified record aliases directory ALSA lib confmisc.c:1334:(snd_func_refer) correction evaluating name ALSA lib conf.c:5178:(_snd_config_evaluate) usability snd_func_refer returned error: No specified record aliases directory ALSA lib conf.c:5701:(snd_config_expand) Evaluate error: No specified record aliases directory ALSA lib control.c:1528:(snd_ctl_open_noupdate) Invalid CTL default cannot unfastened mixer: No specified record aliases directory

I tried reinstalling alsa-utils. Didn't help.

  1. System Profiler and Benchmark doesn't show immoderate audio devices anymore. Same goes for PulseAudio. However, moving sudo lspci -v | grep -i audio does show 00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

  2. sudo ubuntu-drivers autoinstall returns All nan disposable drivers are already installed.

I cognize it's astir apt annoying to reply questions for illustration that, because fundamentally I did it to myself. But I really don't cognize really to move guardant from present and would very overmuch admit immoderate guidance.
