Hello, i just bought this model and when I plug my headphones in my computer, I continuously get this hissing noise on Ubuntu. I don't have this problem on Windows 11. This problem doesn't show up when headphones are unplugged. It is really bothering since I need to work on Ubuntu. I tried some sound tweaks using alsamixer or using different sound codecs but nothing seems to work. Can someone help me? Thanks!

    Are these Bluetooth headphones or plug inns? As I get a slight hissing noise in Win-11 with my AN515-56 in BT mode, as I don't use plug inn type headphones. I get a slight hissing sound (which I didn't get on my older laptop running Win-10 with the same headphones) when the headphones are in pause or between songs or wherever there is no audio or speech and the headphones are idle but they are perfect whenever there is music or speech playing. If you get this hissing noise and its audible when playing music try to reinstall the driver or update the driver but be careful as the new Win-11 drivers especially for the Killer AX1650i 160MHz Wi-Fi/BT card don't work from Intel as they mute Bluetooth and they don't work but they work with Wi-Fi. Which happens in my Nitro 5 AN515-56 as I can't update any of the new Win-11 Intel BT drivers for the "Killer AX1650i 160MHz Wi-Fi/BT card" as none of them work except the OEM Acer old drivers as any of the new Intel Win-11 BT drivers (which there are 3 new updates) don't work.

    >>> problem doesn't show up when headphones are unplugged.>>>

    It might help if you could reveal the brand and model number of your headphones.

    First, thanks for your answers.

    This hissing sound seem to concern only the plugged devices, everything works fine with Bluetooth (and this problem is only appearing on my Ubuntu, not on Windows 11).

    I said headphones, but I meant headset, sorry. My headset is a Sennheiser Game Zero (I bought it something like 5 years ago, I don't know where I can find the model number). I tested with another Headset from another brand, and the problem was the same.

    In fact, I found out that my headset's microphone wasn't even detected on Ubuntu. The "fix" I found was to add the line :
    options snd-hda-intel model=dell-headset-multi
    in the file /etc/modprobe.d/alsa-base.conf

    This mic detection fix made the hissing noise a bit quieter, which now only appears when something is playing or when I modify the output volume using the keyboard shortcuts.

    Now at least, when I plug my headset, Ubuntu asks whether this is a headphone, headset, or microphone.

    Do you have any idea on how to make this hissing noise completely disappear?

    I post these results of sudo hdajacksensetest -a in case it could help (first with headset plugged in, second with headset unplugged) :



    I tried to put every gauge in the "green" in alsamixer, but the problem was the same.

    Try this:
    # /etc/modprobe.d/sound.conf
    options snd-hda-intel model=generic

    Do you mean in alsa-base.conf ?

    The intel option should already be included in the alsa  config, What ubuntu distro is installed?

    options snd-hda-intel model=generic
    In alsa-base.conf only made the computer not recognize my microphone again (same for model=auto), so I'm still using model=dell-headset-multi



    And these are all the occurences of the word "intel" in the conf files (the highlighted one is the one that I wrote) :

    echo 0 > /sys/module/snd_hda_intel/parameters/power_save
    didn't work, don't ask me why I tried

    echo -1 > /sys/module/snd_hda_intel/parameters/power_save
    And now it looks like it fixed it!
    I will keep using my computer a bit before confirming it's totally gone.

    But now, can I make this change permanent? The values goes back to 1 when I restart my laptop :/ .

    Ok, I found how to make this change permanent, I added :
    options snd_hda_intel power_save=-1
    in /etc/modprobe.d/alsa-base.conf

    So, to conclude, the full fix to my problem (non detection of the headset microphone + hissing noise) was to add these two lines in /etc/modprobe.d/alsa-base.conf :

    options snd-hda-intel model=dell-headset-multi<br><br>options snd_hda_intel power_save=-1
    Thanks to everyone involved :)

    @theoretical I think I'm having the same issue with my new Acer Nitro 5... I'll describe the best way I can and maybe you can confirm if it's similar.

    When connecting my headset (to the p3 port) and then playing any song/video, if I pause the song/video a few seconds later I can hear a popping song, similar to a crackle or something like that, and after that, playing the song/video again I get some sort of delay in the audio. I've managed to fix that once, but it got worse because I started listening to a constant hissing, as you described.

    Did the fix you've provided, really fixed the issue? Because if yes, I'll definitely try again.

    Hi @reandov , maybe your problem is similar, but I don't remember experiencing any delay.

    I had the hissing noise in my headphones (connected with the jack plug) even when no audio / video was playing. My linux distribution is Ubuntu 22.04.

    And yes, the fix mentioned above permanently fixed the issue. I don't have audio problems anymore :) .

    Please note that the "<br><br>" in one of my messages above isn't written in my /etc/modprobe.d/alsa-base.conf file. The "<br><br>" represents a newline, it shouldn't be showing, maybe that's a bug from this forum, idk.

    I wish you good luck!
