    Re: Sound troubleshooting

    My audio recently stopped working. I upgraded from 13.04 to 14.04 about a week ago, and everything was working fine.
    Yesterday I was using Rhythmbox (which I don't normally use) to listen to some music. I was adding a bunch of files to Rhythmbox's library, and the audio suddenly stopped working. Rhythmbox froze, so I closed it, (I think I may have gotten an error message related to Pulseaudio around this time, but didn't think to take note), and when I reopened it the sound still didn't work. Sound also stopped working in VLC. I figured I had just crashed Pulseaudio, and that a reboot would fix it, but still nothing.

    I went through the troubleshooting steps posted above with no luck.

    Here's the output of running the alsa information script, if that helps:

    Re: Sound troubleshooting

    I've installed Ubuntu 14.10 on a Toshiba Satellite P50-BBT2G22, but I can't get the sound to work. I've kept the Windows 8 partition alive for warranty purposes, and sound works perfectly there. Using "ubuntu-bug -s audio" in the Terminal, it said that PulseAudio was not configured to use the card I want output from (Built-In Audio - HDA Intel HDMI), but pavucontrol hasn't helped anyway (in pavucontrol, under Configuration tab, all options under Built-In Audio claim that they are unplugged [ 3 options say "Digital Stereo (HDMI) Output (unplugged)", 3 more options say "Digital Surround 5.1 (HDMI) output (unplugged)" and an "Off" option]).

    Data on alsainfo and other files are at https://bugs.launchpad.net/ubuntu/+s...x/+bug/1404589 . I submitted it as a bug a few days ago, but it hasn't had any action since then.

    Can anyone help?

    EDIT: Going through the troubleshooting at https://help.ubuntu.com/community/So...otingProcedure

    I came across this (during Step 3):

    !!ALSA Version
    !!------------

    Driver version: k3.16.0-29-generic
    Library version: 1.0.28
    Utilities version: 1.0.28


    Is it a problem that they're not all the same?

    HDMI audio problems

    I have been running Mythbuntu for several years, and I recently did a clean install of 14.04.
    HDMI audio works fine in Mythtv, but I can't get it to work with anything else. I want to use VLC, XBMC, etc in addition to Mythtv.
    I have a NVidia 610 video card.

    In Mythtv setup, the audio device that works is ALSA:hdmi:CARD=NVidia,DEV=1

    When I was running 12.04, I got all the audio working by setting the default audio device by using:
    pacmd list-sinks
    pacmd set-default-sink

    When I run pacmd list-sinks in 14.04 i get
    Code:
    Welcome to PulseAudio! Use "help" for usage information.

    I have made sure nothing is muted in alsamixer, I have tried many different setting combinations in PulseAudio volume control and still can't get this to work.
    Weird thing is, 2 different times I got audio in XBMC and thought I had it fixed, but the next time I opened it I had no sound. I don't want to wreck the audio in Mythtv, so I hate to change much without getting some advice first. Can anyone help me troubleshoot this problem?

    Re: Sound troubleshooting

    Hello
    I have carefully followed all the sound troubleshooting procédure.
    I am in Xubuntun 14.04. As a consequence of following the multiple advices in these procedures, I have many new things in my menu, no more access to synaptic and many other problems.
    Then I found on Internet the following page written by canonical whose title is "top-five-wrong-ways-to-fix-your-audio"
    dhttp://voices.canonical.com/david.henningsson/2012/07/13/top-five-wrong-ways-to-fix-your-audio/o.

    Almost all these things are included in the troubleshooting procedure. It seems to me it is a real problem.
    My configuration is broken. I am going to re-instal it from scratch and I will not follow the troubleshootingprocedures.

    I think I got my problem solved.
    I disabled PulseAudio
    Code:
    echo autospawn=no > ~/.pulse/client.conf
    pulseaudio -k
    I seem to be getting audio everywhere I need it now
    I have no idea if this breaks something else, but it works for me so far

    Re: Sound troubleshooting

    Hi there.

    I've followed the guide at the start of this thread but whatever I do I can't get my Traktor Audio 6 card to work since installing 15.04 (it worked with no special setup in 14.10).

    I posted on AskUbuntu here, http://askubuntu.com/questions/64553...-15-04-upgrade

    Sound is fine via the onboard card, but not via my external. If I run `pactl list` I see all my cards listed, and if I run `aplay -l` I see my cards correctly, but they don't show up in the sound selection app on the system menu bar.

    If I run alsamixer and select the card I want to use, all channels for the card are shown as disabled. See screenshot below.

    I tried creating an /etc/asound.conf file as per the sticky guide but that didn't help.

    I'm not sure where to go next. Any ideas?

    Thanks!

    Ludo
