Mam dokładnie ten sam problem i nie mogę sobie poradzić
Po wpisywaniu w terminalu alsaconf wyskakuje:
Junior@linux-bfuh:~> alsaconf
Program 'alsaconf' is present in package 'alsa-utils', which is installed on your system.
Absolute path to 'alsaconf' is '/usr/sbin/alsaconf', so it might be intended to be run only by user with superuser privileges (eg. root).
bash: alsaconf: command not found
A po wpisaniu alsamixer:
Junior@linux-bfuh:~> alsamixer
ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Connection refused
alsamixer: function snd_ctl_open failed for default: Connection refused
Proszę o pomoc
