[Bug 1629661] Re: Hissing sound in headphones
** Changed in: linux (Ubuntu) Status: Incomplete => Opinion ** Changed in: linux (Ubuntu) Status: Opinion => Confirmed ** Description changed: Ubuntu 16.04 on 64 bit produces hissing sound (just by my - far from being 'musical' - ear, it sounds like a sinus wave with frequency about 1KHz or so) on headphones. Interestingly, after boot this does not happen and usually can be hear only after the first application which makes any sound (but not always, sometimes it starts later). But if any time it starts, it remains, whatever I do, exiting the application (which makes the sound) even by killing pulseaudio process, etc. I've read a lot on this issue but usually - it seems - always notebook problems mentioned, however it's a desktop machine (Asrock FM2A88M extreme4+ motherboard, AMD A6-6400K CPU, integrated audio). It seems it uses snd_hda_intel kernel module though. I've tried advices mentioned by various resources throughout the net, disabling powersave problems, using hdajackretask from alsa-tools-gui, etc, but they didn't help.

Sorry about my English, so I meant that I didn't own the machine itself, so I have no experience just since I use that PC, and it's only two weeks or so. Also, I've just discovered that the annoying sound is there even right after switching the machine on, without any OS loaded too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629661 Title: Hissing sound in headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1629661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Quite odd ... But it seems there is sometimes a louder hissing sound, but the other one is more frequent issue: a not so loud but annoying one. This second _seems_ to be cause (I have no idea about the reason!!) by an XBox 360 controller. If it's plugged to the USB port, the sound can be heard in sync with the blinking "circular green LED" on the controller. After it stops blinking, the sound remains. If I unplug from the USB port, the annoying noise is stopped. Maybe it's not even a software issue, but some kind of hardware, interference, or whatever? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629661 Title: Hissing sound in headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1629661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
