Public bug reported: [Impact] When playing audio from HDMI/DP port on AMD W6300 gfx, there's always white noise. It will disappear after suspend/resume. Disabling ASPM on W6300 also fix this.
[Fix] Backport a fix from AMD on https://www.spinics.net/lists/amd-gfx/msg93796.html https://www.spinics.net/lists/amd-gfx/msg93797.html [Test] 1. Power on the Desktop installed with AMD W6300 gfx 2. Connect a monitor with either HDMI or DP cable. 3. Change the audio output port to HDMI/DP and play audio. 4. Verify if there's noise from the audio output [Where problems could occur] Only observed on AMD W6300. The fix revise the ASPM L1 inactivily time out on NAVI10 GPU series. The impact should be only for this particular GPU series. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-oem-6.1 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Affects: linux-oem-6.1 (Ubuntu Jammy) Importance: Undecided Status: In Progress ** Also affects: linux (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: linux-oem-6.1 (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-oem-6.1 (Ubuntu Jammy) Status: New => In Progress -- 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/2024449 Title: Fix audio white noise while play from HDMI/DP port on AMD W6300 gfx Status in linux package in Ubuntu: New Status in linux-oem-6.1 package in Ubuntu: New Status in linux source package in Jammy: New Status in linux-oem-6.1 source package in Jammy: In Progress Bug description: [Impact] When playing audio from HDMI/DP port on AMD W6300 gfx, there's always white noise.
