Message Signaled Interrupts (MSI) Question


Recommended Posts

Is it true that MSI mode is not really needed if the IRQ for the device is NOT shared by another device (Meaning the device has its own dedicated IRQ)? If this is true then it explains why my video card has MSI mode turned off when it has its own IRQ and turned on when it is sharing the IRQ with other devices.

I don't need to jump to conclusions and to be polite, you would be referring to sarcasm would you?

I'm trying to prove a point with these A**'s over in the Creative Reddit forum. They really pray to the Message Signaled Interrupts as if it is the god that fixes all latencies and audio dropouts (Which is not the case). What is causing the issues they so dearly complain about is UEFI firmware that is poorly written. Actually it is the fault of 3: Microsoft, Driver makers and UEFI firmware makers.

Funny, cause Microsoft already fixed it.  https://docs.microsoft.com/en-us/windows-hardware/drivers/audio/low-latency-audio

 

Obviously they can't control the other two issues, or the software people use that uses ancient audio paths.

Hello,

 

Creative Labs' SoundBlaster cards were somewhat persnickety on ISA and PCI buses, so I don't necessarily know if I would blame current problems on PCIe bus engineering issues.  That said, there are not a lot of players left in the discrete sound card space (ASUS and EVGA come to mind), so options are limited if you want to do/use something beyond the capabilities of most on-board audio subsystems.  My primary desktop system is an EVGA Z370 Classified K which features "Creative's Sound Core 3D Audio" that I believe is the same as the Recon 3Di and hasn't worked for the last couple of versions of Windows due to its drivers not being updated to fix architectural issues that cropped up.  So, I am definitely sympathetic to anyone trying to troubleshoot issues with Creative Labs sound cards.

 

One of the things I noticed being given as a kind of universal panacea over in the subreddit was the installation of some kind of modded driver pack.  I don't know if that is the case that it will help, but it definitely does say something if their customers have to rely on homebrewed device driver support because the company can't be bothered to update its Windows drivers.

 

Regards,

I actually have the following:

*Asus Maximus XI extreme motherboard (Z390)

*with the Sound Blaster AE-9 pcie sound card.

*Intel Core i9 9900k

*32Gb RAM.

*Samsung 970 Pro NVMe 1Tb

_______

I've come to the conclusion that it's A UEFI Firmware issue that can be fixed through an update, but creative needs to work closely with the motherboard makers to fix the audio dropout issue.

It’s over his head so he is belittling instead of helping.

    • UK planning measures to stop illegal content from going viral by Usama Jawad Image via Pixabay A few days ago, we learned that the UK's digital regulator Ofcom has mandated adult websites like Pornhub to put robust age check mechanisms in place to ensure that age-inappropriate content like pornography is not readily available to minors. Now, the government-approved authority has set its sights on a new target. According to an announcement on its website, Ofcom is now holding a consultation period for a set of measures it is proposing to curb the spread of illegal content online. These methods are a part of Ofcom's "Year of Action" initiative, where the regulator is taking decisive practical actions to ensure the online safety of the UK's citizens. Ofcom is proposing the implementation of better recommender systems and crisis response protocols to restrict illegal content from going viral online. In addition, it has also proposed the utilization of proactive mechanisms like hash checks for illegal images to nip the problem in the bud and not even allow any such visual content to be published online. Furthermore, the regulator will be asking tech firms and social media platform owners to leverage artificial intelligence systems in order to detect content like fraud and suicide. People who regularly engage in the practice of publication of illegal content online will also be punished with new sanctions. Lastly, Ofcom wants to build upon its existing child protection codes and capabilities online. It is planning to do this by placing restrictions on interactions between minors and streamers during livestreams. It will urge website owners to block users who share child sexual abuse material (CSAM) and is also proposing the development of AI tools to detect grooming activities and CSAM. The consultation period is open until 5pm on October 20, 2025. Ofcom is soliciting feedback from "service providers", law enforcement authorities, and the public until that deadline to finalize its proposal.
    • What are you talking about? I have had 4 Samsung fold devices and they all have the crease. It is not as noticable when facing straight on but its still noticable.
    • Well they would be right 90% of the time.
    • It didn't help but it certainly wasn't the cause.
