Aspire E5-774G Sound and Latency Problems

Hi there,

 

recently bought an Aspire E5-774G after using an older i3 laptop for years. The machine is equipped with i5-7200U/940MX(2GB)/8GB and running Win 10 pro. Not exactly a games machine but should run some more recent games.

 

The Aspire had Linux installed, which I replaced with Win 10 pro. Up to now, I installed most drivers from Acers support page (chipset, NVidia, TurboBoost, Bluetooth and others, I think LAN and WLAN is missing but working well). The power button doesn't trigger hibernation and I don't see any action from caps/num-lock but that's a minor problem. The Aspire is flashed to the latest BIOS.

 

With this fresh installation I tried Alice: Madness returns and noticed, while having fluent graphics, audio distortions/stuttering. I checked the CPU load and found interrupts to eat about 15% CPU time. The LatencyMon revealed high latency on hdaudbus.sys and high pagefault-number.

 

I was able to reduce CPU load down to about 5%  by just deactivating intel audio, but that improvement didn't survive reboot. Still, intel audio is not active.

 

I need some assistance here because I think the Aspire can do better. What can I do? I know there are tons of posts on this problem with nearly no solution but hope dies last.

 

Thank you very much for any help,

 

Thomas

Hallo,

 

ich habe ein neues Aspire E5-774G mit Win 10 pro ausgestattet, die wesentlichen Treiber von der Support-Seite installiert, alle Updates laufen lassen und bemerke nun eine permanente Auslastung der CPU zwischen 10 und 20%, wobei die Systemunterbrechungen dominieren.

 

Der LatencyMon zeigt eine hohe Zahl an pagefaults und eine zu große Latenz insbesondere des hdaudbus.sys Treibers.

 

Das Laptop hat eine i5-7200U CPU und eine NVidia 940MX (2GB) GPU verbaut, das RAM umfasst 8GiB.

 

Im Spiel Alice: Madness returns von 2011 bemerke ich massive Tonprobleme. Kurzfristig habe ich die in den Griff bekommen durch Deaktivierung des Intel-Audio-Geräts im Gerätemanager. Diese Verbesserung hat leider den Neustart nicht überlebt, obwohl das Gerät nach wie vor inaktiv ist.

 

Kann jemand in dieser Sache helfen?

 

Danke :-)

 

Thomas

    Hi!

    This problem is observed at many, watch a subject.

    Promised to transfer it in technical support to the technical specialists, but told that the decision can take several months. Something like this.

     

    If that, then I have E5-774G too

    Yesterday I have

     

    (1) deactivated all devices not necessary for running a basic offline-system to no avail

    (2) installed the remaining Acer drivers to no avail

    (3) got the latest drivers for the 940MX and the Realtek chip to no avail

    (4) booted without non-MS-services to no avail

    (5) attached a Behringer UFO202 to see if it can play in-game audio without distortions to no avail

     

    Next up: Booting with no non-MS-services and no auto boot programs.

     

    I'm currently spending all after-work hours for troubleshooting :-(. Please guys, can anyone confirm that the E5-774G is able to run Win 10 without this kind of latency and load? Is it a lost cause?

    Thanks a lot, Niko!

     

    What I haven't tried is deactivating the Realtek driver and using my Behringer. That would be the solution for playing games. When I'm back home I'll give it a try.

     

    Clearly, we're not alone with our Acers. Several MOBOs are reported to have problems with Win>7. Either it is something in the recent Windows kernels or some components are buggy. Acer appears to be a victim of this situation and currently I wouldn't buy *any* piece of computer hardware until these issues are resolved by whoever is responsible.

     

    Best,

    I have a similar problem, i use ezDrummer2 with my acer itro 5; i7 8500 1.8Ghz; i use it to play my eDrum with the ezDrummer2,When using with ASIO driver i should have no delay in output, but this system i am using cannot make the sound output as if there was no delay; hence it is not possible to play along with music; Could this be because of the CPU clock speed, or ist it with the sound system of this acer nitro5
