S0 Sleep State causes bluetooth audio stutter ?

[magrega]

Hi! I have an Asus Vivobook S 14 M3402RA laptop with an Intel AX210 WiFi/BT module.
Laptop is running Windows 11 24H2 but I also tried Windows 10.

I have a major issue. When my laptop enters sleep mode while bluetooth is on and playing music, it starts stuttering a bit, skipping audio from time to time.

I tried a tremendous number of different drivers and updates but it stays the same. The only things I could discover:

• If I disable AMD GPU driver in Device manager, the basic GPU driver comes into play and bluetooth stutter stops but I can't use an external monitor.
• If my AMD GPU drivers are activated any music that is played (both locally from hard drive or online, like from youtube) stutters but if I put on a twitch stream and lock my screen, the audio is fine.

And there's another problem but it has less priority since it doesn't bother me that much. There's a long bios start. If the laptop is plugged in, it might take up to 20 seconds before asus logo appears, if it works from battery then it might turn on only from second or third power button press. Installing BIOS 304 from 5402 resolves this. Also coming out of sleep mode sometimes makes laptop freeze. The screen doesn't turn on unless I either plug it in or plug it out.

It's somehow connected to how the laptop enters S0 sleep state which is impossible to turn off and go back to S3. Any ideas would be appreciated. Also It would be fantastic if someone from ASUS tech department could take a look since I've been exploring this problem for more than a year now and not a single repair service was able to fix this.

I have a more detailed discussion of this here.

To avoid any misunderstanding, based on your description, can I understand that you have previously replaced the WiFi/BT module?
If you have replaced the relevant module, as the laptop has been disassembled and parts have been replaced, we need to first clarify whether the issue might be caused by a hardware malfunction (especially since you have already reinstalled the drivers and restored the system but the issue persists).
Therefore, under the current circumstances, we recommend taking the laptop to a service center for further inspection.
Sorry for any inconvenience it may be caused.

The WiFi module is the only thing that was replaced. The original module showed the same behavior. Please read into what I write. I already said that I even tried using an external bluetooth dongle, it's all the same. There's something wrong with power management or the GPU driver.

I've been to repair centers multiple times in different cities.
The reason I replaced WiFi module was because it was interrupting out of the box right after purchase but I still have the original module and can put it back but that is unnecessary.

Unfortunately, for laptop products, if the components on the motherboard have been altered, we cannot determine whether the reported issue is caused by the replacement of other parts. Therefore, we recommend taking the laptop to a service center for further inspection. We apologize for any inconvenience caused.

If I put the original wifi module back will you be able to continue helping me?
Also I wanted to ask did my .wim file reveal anything?

If you recorded the relevant files after changing the hardware, we cannot comment on those files because the replaced hardware was not provided by us. As mentioned in our previous response, since we cannot verify the current actual condition of the machine and you have already attempted to restore the system but the issue persists, we still recommend that you send the laptop to the service center for further inspection. We apologize for any inconvenience caused.
