• [gentoo-user] Sound not sounding

    From Peter Humphrey@21:1/5 to All on Wed Mar 23 18:00:01 2022
    Hello list,

    The USB sound dongle on this workstation has stopped working, but only for me. The system settings Audio setup window detects it but no sound is heard (I nearly said none appears :) . It worked a week ago, and it still works if I
    log in as a new user. Windows 10 has no trouble with it either. Nothing has changed in the kernel setup, and all the right modules are loaded.

    Could I have something poisonous in $HOME? I'm awfully tired of creating new user accounts for myself. And this reminds me of the problem with Konsole not shutting down properly:
    1. https://bugs.gentoo.org/show_bug.cgi?id=819459 and
    2. https://bugs.kde.org/show_bug.cgi?id=445862 .

    A comment on [1] suggested something in my $HOME was to blame, but nothing
    came of it.

    (The motherboard chip failed months ago, so I bought a UGreen USB dongle. System settings detects that, and the audio output of my GPU, as well as the dongle.)

    Hi Peter,
    Sorry for the problems.

    Please provide info about your setup such as desktop environment and
    how you set up your sound system. ALSA? pulseaudio? Something else?

    I have a new machine in which I have not yet used a previously working
    USB sound device - a gen 3 Focusrite Scarlett 2/2. I'm happy to invest
    a little time to bring it up sooner vs later if there's a way to help.

    Cheers,
    Mark

    So by 'Plasma' you imply KDE to me. Am I correct in that?

    What floors me is that two users on the same machine get different results.


    Agreed but if it's KDE then generally that implies pulseaudio and users can have
    different configurations. Assuming generalized KDE for the moment, then

    System Settings -> Audio

    should show your playback devices. Possibly the setting got switched to
    an HDMI output on your video card or to the chipset sound device
    and isn't USB at the moment?

    HTH,
    Mark

    Also, assuming it's KDE then also run pavucontrol-qt (or whatever it's
    called on your system) to ensure you see the application generating
    audio is actually doing what you think it is - there's an app-by-app
    set of VU meters showing where KDE is sending audio in terms of
    which hardware output.

    I.e. - KDE can send audio from different apps to one or more
    hardware devices at the same time. pavucontrol should allow
    you to see how this is happening at any time. I have it in my
    favorites.

    Good luck,
    Mark

    Yes and no ...

    To a rough approximation, KDE is Qt4. Plasma is Qt5.

    Interesting. Having moved to Kubuntu it's just Kubuntu to me, and it's
    what I don't like about becoming primarily a Kubuntu user as you end
    up much more 'detached' from all this stuff. However my important apps
    also 'just work' and vendors provide answers which they seldom did
    when I was running Gentoo.

    As for Peter, I suspect given a little time the response I provided
    should help him. Here I hooked up my Focusrite USB device while I
    already had Chrome playing through a different spdif output.
    pulseaudio changed the audio to the USB device and using pavucontrol I
    switched it back to the spdif output. Hopefully Peter will have some
    similar result.

    Cheers,
    Mark

    <hehe> Yeah, ain't that the truth! I'd likely be a Gentoo user if anyone
    built and maintained a 'standard', stable distro, something delivered
    in primarily binary files. I just lost patience dealing with all the issues
    you guys deal with daily.

    I still have a bit of my gentoo-users folder going back a few years.
    One of the older threads I saved was actually talking to Peter in
    2005. I built my first Gentoo machine in 2001, about a year after
    Daniel started the distro. Kudo's to Peter for making it this far!

    [snip ...]

    There is this experiment making available binary packages based on Gentoo profiles, care of dilfridge:

    https://dilfridge.blogspot.com/2021/09/experimental-binary-gentoo-package.html

    Although the article mentions a systemd profile, I've tried it with an openrc installation and it worked fine. Binaries were downloaded and installed as part of a normal update, just as advertised. I didn't try any packages in the gentoo toolchain, as this could break things, but I can see the benefit of using this facility at least selectively to bypass long compilations. -----BEGIN PGP SIGNATURE-----

    If you have Gentoo, you have to resist the temptation to give in to
    despair. If you do, good things usually follow.

    I still can't escape the conclusion that something in my home
    directory is
    interfering with sound output.
    Just to confirm - pavucontrol shows the sound device as properly
    enabled on the Configuration tab, shows the correct output port for the device on the Output Devices tab, and shows the sound source being sent
    to the right device on the Playback tab (with volumes up) but still no
    sound from the speakers? Do any of the sound meters show any apparent activity? Can you see any difference between the pavucontrol display
    as youurself and as the user for whom sound does work?

    I would guess that if it is something in your home directory, it is
    most likely a configuration setting, probably under .local or .config.
    I see several files under ~/.config/pulse. You might try moving those elsewhere and restarting pulse ("pulseaudio -k" then restart
    pavucontrol) and comparing the before and after (if there is any change
    in behavior) and possibly also comparing those files from your home dir
    and those for the working user.

    One other thing I might look for (I'm grasping at straws here, but also
    under .local or .config) is anything related to device initialization, perhaps USB settings.

    Sorry, if that was actually in the original post I just didn't understand.

    Jack's response to you was more complete and duplicates my thinking
    about how to approach debugging.

    To answer one of your earlier questions, but I doubt it applies in the
    case of a simple USB sound device, it is possible for other programs
    to program certain sound cards in ways that Alsa & pulseaudio would
    not know about. I've used an RME HDSP9652 studio sound card
    for about 15 years. It has 52 inputs, 52 outputs and lots of internal
    hardware routing that general Linux sound doesn't know about and
    cannot control. It's configured using two apps (hdspconf and
    hdspmixer) to do a lot of special things that are recording studio
    specific. At times I've misused these programs and had a lot of
    mysterious problems. That said I think it's very unlikely anything
    like this applies in your case, but technically it's possible.

    Good luck getting this solved. Weird stuff.

    The system settings Audio setup window detects it but no sound is heard

    Run "alsamixer" (it's a command-line tool) and in the text UI that
    appears, press F6, select your USB audio device, and then check if it's
    muted or the volume is 0.

    PulseAudio generally uses the ALSA sound mixer to change volumes, but
    not always. For some devices, it uses a software volume control that
    doesn't use the ALSA volume controls. So if those are set to 0, there
    will never be any sound.

    To answer one of your earlier questions, but I doubt it applies in the
    case of a simple USB sound device, it is possible for other programs
    to program certain sound cards in ways that Alsa & pulseaudio would
    not know about. I've used an RME HDSP9652 studio sound card
    for about 15 years. It has 52 inputs, 52 outputs and lots of internal hardware routing that general Linux sound doesn't know about and
    cannot control. It's configured using two apps (hdspconf and
    hdspmixer) to do a lot of special things that are recording studio
    specific. At times I've misused these programs and had a lot of
    mysterious problems. That said I think it's very unlikely anything
    like this applies in your case, but technically it's possible.

    Good luck getting this solved. Weird stuff.

    I usually troubleshoot such problems as Peter has, by creating a vanilla user account to compare settings against my normal user. Using diff between the two accounts ~/.pulse files tends to reveal anything lurking in the undergrowth. 'pactl stat' may also reveal any user differences.

    Another thought, it may worth checking group membership, audio and plugdev/ usb(?), are the same for all users. I mention this, because some recent
    update had me adding a user to the usb group to be able to use a USB scanner, which for many years had worked fine with plugdev membership only.

    Run "alsamixer" (it's a command-line tool) and in the text UI that
    appears, press F6, select your USB audio device, and then check if it's
    muted or the volume is 0.

    No alsamixer here, so I installed alsa-utils and did as you suggest. All seems fine: volume at full, muting off.

    PulseAudio generally uses the ALSA sound mixer to change volumes, but
    not always. For some devices, it uses a software volume control that
    doesn't use the ALSA volume controls. So if those are set to 0, there
    will never be any sound.

    There was sound just fine until one day last week. I'm not aware of any change by which I could have affected sound - just routine daily upgrades and ordinary use of the system.

    Nothing has changed in the kernel setup, and all the right modules are loaded.

    I gave up: not just life is too short - so was my sanity. I installed a new stable system from bare metal, created a new user account and now I have a working system.

    Oddly, the system announces that it's found the USB sound dongle when I switch the speakers on, even though the dongle has been there all along. Yet another of life's little mysteries, I suppose.

    Thanks are due to many who tried to help, so thank you all.
