3) AE-7/AE-9 audio dropout (including channel swap on X570 boards)
10/12 – An AE-9 / AE-7 beta driver that has been tested internally to resolve issues with systems that have had the audio dropout issue is now available. You can download the driver here –

10/11 – Good news. With the feedback we’ve received from various users (many located on here) we’ve been able to reproduce and isolate an issue that leads to this audio dropout. The internal beta has rectified the problem internally and we will be releasing to the public within the next few days. We will update here once again once the beta is ready for distribution.
12/02 Update: the latest driver is available on Windows Update. We are still looking into audio drop issues when memory is overclocked.
12/30 No Update.
02/05 No Update.
03/02: Currently, the outstanding audio dropout reports are related to high-speed memory (3000+ MHz). We are still investigating this issue, as it is only seen on certain systems.
03/21: We have invested in a new equipment that would help us to expedite and improve our capacity in the investigation of this issue. Due to the worldwide COVID-19 situation affecting delivery of the equipment, we estimate to be able to do that in June 2020.
04/25: The delivery of the equipment we are getting to improve on our capacity for investigation of this issue has been brought forward to early May. We are also working to gather the relevant equipment and systems required to investigate the issue due to COVID-19 isolation measures affecting the way we can work and look into issues. We are still trying to work as best we can within the bounds of such measures, and we hope the community would understand and give us more time during this trying time.
06/14: We have been studying the issues on a X570 system since obtaining the new equipment at end May 2020. The new equipment has allowed us to identify unusual events that occurs when audio drop or channel swap occurs on X570. Currently investigating the issues based on the additional information found. We are currently focusing on the X570 boards for the investigations which seems to be what majority of users facing the issue is on, and will see if the fix for the issues will help users on other boards.
08/02: We are working with AMD to investigate the issues seen on the X570 chipset motherboard.
09/11: We are still working with AMD on the investigation of the issues. As details of the investigation progress cannot be published, we hope everyone can be patience on this while the investigation continues.
10/09: AMD has advised to adjust below settings which may help to resolve the issues.
11/09: We are still working with AMD on the investigation of the issues. For those who encountered issues, please refer to below settings suggested by AMD.
11/11: We are still working with AMD on the investigation of the issues. For those who encountered issues, please refer to below settings suggested by AMD.
12/10: We are still working with AMD on the investigation of the issues. AMD has updated us that they do not guarantee any specific overclock amount and only guarantee JEDEC memory operation. Given their experience through many DIMMS/CPUs/Motherboards can likely hit DDR3600/1800MHz FCLK with the right timing and voltage settings. For those who encountered issues, please refer to below settings suggested by AMD.
01/08: We are still working with AMD on the investigation of the issues. AMD has updated us that they do not guarantee any specific overclock amount and only guarantee JEDEC memory operation. Given their experience through many DIMMS/CPUs/Motherboards can likely hit DDR3600/1800MHz FCLK with the right timing and voltage settings. For those who encountered issues, please refer to below settings suggested by AMD.
a) Disable PCIe Link State Power Management and other power saving settings in BIOS. In general, power management can add latency to devices wake up.

b) Disable CPU Global C-State. From AMD findings, disable this setting seems to have improvement on bus completion latency.

02/08: After investigation in cooperation with AMD, we have concluded that the audio distortion you are experiencing is due to an unstable processor overclock. Data for peripheral devices, such as audio cards or USB devices, traverses the Infinity Fabric on AMD Ryzen processors. The Infinity Fabric exists within the Ryzen CPU, and it connects most of the ports and slots on a motherboard to the CPU cores so they may communicate. If the user has implemented a Fabric/DRAM overclock that is not truly stable, communication errors in the Fabric/DRAM can manifest as audio distortion or delays. AMD Ryzen processors officially support DDR4-3200 (1600MHz Infinity Fabric clock), and speeds beyond this point cannot be guaranteed or supported by the product warranty. While we understand and appreciate that users want to overclock their system, instability is always a risk, and such instabilities may not be revealed by conventional memory stress testing.
