I have a problem with my sound suddenly stopping working (I'm on Mint 18.2 based on xenial, asus x555l). The work around is to reboot.
Another work around without rebooting: disable pulseaudio, first by turning off autorespawn https://askubuntu.com/questions/8425/how-to- temporarily-disable-pulseaudio and then pulseaudio --kill Then sudo alsa reload alsactl init aplay /usr/share/sounds/alsa/Front_Center.wav This responsed (with no audio playback): ALSA lib pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave aplay: main:722: audio open error: No such file or directory However, this works: aplay /usr/share/sounds/alsa/Front_Center.wav --device=plughw:CARD=PCH,DEV=0 Then "pulseaudio --start" and my audio is back and working! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1341890 Title: [X550LA, Realtek ALC3236, Mic, Internal] No sound at all Status in alsa-driver package in Ubuntu: Confirmed Bug description: I've been trying to fix this myself for a while now, and just a day or two ago, the speakers stopped working, too. Neither the internal nor external speakers I've been using with my laptop have been working, with two exceptions: the bongos noise when the login screen comes up, and the tones made during a system test. I have tried the commands "alsamixer" and "gstreamer-properties" in terminal and have had success with neither of them, and have also tried using the pulse audio volume controls to no avail. My assumption is that there is an issue with the drivers, as even the microphone produced a few sporadic noises ONLY when I was playing with the mic volume controls, but at no other point in no other program has it been so responsive.
