• Sound problem on new laptop

    So, my new laptop has arrived. According to the manual it comes with a Sound Blaster X-FI MB5 sound card and it has a built in subwoofer. Unfortunately I haven’t been able to get the subwoofer working and the general sound quality is rather poorish. Any ideas how to get that soundcard and the subwoofer working properly?

    first i would take a look what alsamixer gives you, may subwoofer is muted ?
    Press [F6] to choose your card…

  • @joekamprad
    The subwoofer isn’t even listed in alsamixer.

  • there is this http://www.alsa-project.org/alsa-info.sh skript, to give advanced information on soundcards

  • Here’s the output of that script on pastebin

  • System summary and boot up messages:

    lspci > log.txt && lsusb >> log.txt && dmesg >> log.txt && cat log.txt | curl -F [email protected] https://ptpb.pw/?u=1

    Is what systemsummary give as your soundcard…
    Do you have alsa-firmware installed?

  • alsa-firmware was not installed. Installed it, rebooted, no change.

  • pavucontrol is also good to see if pulseaudio is causing this…
    But it is a common problem that subwoofer is not working under Linux…

  • Already checked pavucontrol, no subwoofer visible there either.

  • To make it clear to me …
    is there a subwoofer inside the machine, or you can plug one like a surround system?

  • The subwoofer is built into the case of the laptop.
    I have noticed that there is a digital stereo iec 958 device available, but whenever I switch to it, the whole sound gets muted.

  • there is maybe a huzzle with surround sound aka stereo vs. 5.1… i remember stuff like this from former systems…

    pactl list sinks

    Will give info too…

    and for KDE there is plasma-pa

  • Thats the output of pactl list sinks
    If I switch to digital stereo iec 958 in plasma-pa, I have no sound at all.

  • So subwoofer is not there in any ways… could be wrong driver/module

    some noise:

    speaker-test -c 6

    5 - Bass
    Bass stays mute though, all other channels give me some noise.

  • seems to be a driver problem and i can not find any option for your device…
