In case this helps the developers, I've been seeing users of Linux Mint experiencing this recently. The common factor has been the the D3 state of the speaker volume, headphone volume, capture volume/switch NID's Running the following command has always worked to get the headphones working: sudo hda-verb /dev/snd/hwC0D0 0x03 SET_POWER 0x0 Doing the same for the speaker NID (0x02) has been hit and miss, mostly miss, and so far no one has tried the Capture NID. Dell Inspiron's of various models seem to have been affected. Also, HP Pavilion All-in-One's of a few different models that have ALC225 have also experienced this. 4.15.0-96 was the last working kernel for most if not all of these users. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1875985 Title: [Inspiron 13-5368, Realtek ALC3253, Speaker, Internal] No sound at all after kernel upgrade to 4.15.0-99-generic on Ubuntu 18.04.4 Status in linux package in Ubuntu: Confirmed Bug description: VERSION="18.04.4 LTS (Bionic Beaver)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 18.04.4 LTS" Running it in the flavour of Xubuntu. Just like in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1875916 my sound stopped working with the new kernel "4.15.0-99-generic #100-Ubuntu SMP Wed Apr 22 20:32:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux". Rebooting into "4.15.0-96-generic #97-Ubuntu SMP Wed Apr 1 03:25:46 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux" sound works again. With 4.15.0-99-generic I do see a signal on the meters of the sound/volume control app, but physically there is no sound on either internal speakers nor on the headphones. With 4.15.0-96-generic everything is back to normal. My touchpad is working though (#1875916 seems to suggest that the touchpad stops working with 4.15.0-99-generic).
