    Re: Sound troubleshooting

    hmmm it looks like maybe it's already fixed in the new alsa builds.
    basically nothing worked and I nearly gave up but found this guide
    https://help.ubuntu.com/community/So...otingProcedure

    step 4 and just adding the ppa and installing the hda audio daily build works

    sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily

    sudo apt-get update

    sudo apt-get install oem-audio-hda-daily-dkms

    reboot

    then both alsa and pulse audio outputs work

    Re: Sound troubleshooting

    Dear friends,

    Using the procedure in https://help.ubuntu.com/community/So...otingProcedure, I can achieve working sound.

    Problems:

    This does not last across reboots. (laptop, so often rebooted)
    Pavucontrol does not mute system sounds. (for anyone coming across this, one can kill the sounds in dconf, so this much solved)

    Running mate desktop on upgrade from 18.04. (not ubuntu mate the distro)

    there were a number of vicious problems with update, but now all is running smoothly except for sound.

    It is a nuisance to have the noise, and worse, to have to execute that command every time I reboot, as i travel a lot.

    Any suggestions?


    after running the command from the link above:


    Code:
    cat /proc/asound/{version,cards,devices,hwdep,pcm,seq/clients}; ls -l /usr/share/pulseaudio/alsa-mixer/paths/; sudo rm /etc/asound.conf; sudo rm -r ~/.pulse ~/.asound* ;sudo rm ~/.pulse-cookie; sudo apt-get update; sudo apt-get install aptitude; sudo aptitude install paman gnome-alsamixer libasound2-plugins padevchooser libsdl1.2debian-pulseaudio; sudo lshw -short;ls -lart /dev/snd; find /lib/modules/`uname -r` | grep snd ;cat /dev/sndstat; lspci -nn; lsusb; sudo which alsactl; sudo fuser -v /dev/dsp /dev/snd/* ; dpkg -S bin/slmodemd; dmesg | egrep 'EMU|probe|emu|ALSA|alsa|ac97|udi|snd|ound|irmware'; sudo /etc/init.d/sl-modem-daemon status; sudo grep model /etc/modprobe.d/* ; sudo dmidecode|egrep 'anufact|roduct|erial|elease'; lsmod | egrep 'snd|usb|midi|udio'; pacmd list-sinks; aplay -l; sudo alsa force-reload;  ubuntu-support-status ; sudo lshw -C sound






    reading the output, it appears that timidity daemon races with pulse. Thus, the most practical solution is to purge timidity for the time being, since there are other ways of playing midi right now.

    This is written to help anyone searching for what may not be an obvious problem.


    Best,
    M

    Re: Sound troubleshooting

    I think I have a new and interesting sound failure in Ubuntu 18.04 on an Intel Nuc hooked up to my TV via HDMI. Sometimes there is sound, sometimes there is no sound. I have gone through several troubleshooting guides and still haven't figured it out. I have narrowed it down to a problem with certain videos on YouTube and certain songs on Pandora/Slacker/Spotify. Netflix and Amazon Video both play sound consistently. I am primarily using Firefox, but I have verified the no-sound problem with Chrome as well. I thought it could be a licensing issue, but it happens sometimes with YouTube videos that have no music. Any ideas?
