Public bug reported: I have an Ubuntu 18.04 installed on my DELL 7490 laptop. Kernel version is: 5.3.0-40-generic
When I plug in one of my headphones and start to play sound I immediately start to hear white noise in the earphone. After I stop the music the white noise still remains for 5 more seconds, after 5 seconds it stops. I tried with different headphones, the only difference between them is the volume of the white noise. I tried several ways to fix the problem but without any luck. lspci -nnk | grep -iA2 audio output: 00:1f.3 Audio device [0403]: Intel Corporation Sunrise Point-LP HD Audio [8086:9d71] (rev 21) Subsystem: Dell Sunrise Point-LP HD Audio [1028:081c] Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_skl sudo aplay -l output: **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC3246 Analog [ALC3246 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4] Subdevices: 1/1 Subdevice #0: subdevice #0 Thanks for your help in advance! ** Affects: ubuntu Importance: Undecided Status: New ** Tags: alc3246 dell headphones hiss noise white -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869080 Title: White noise during sound playing and after sound stopped for 5 seconds in headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1869080/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
