Hi! I wrote this to your e-mail, but it didn't arrive, I guess. I want to say that I REALLY appreciate your efforts in making and maintaining UNi Xonar mod driver. I bought a Xense recently and I'm still using the official driver without any problem. But I have some questions about your mod.
1- what exactly did you change to decrease the DPC latency? Is there any downside in doing this?
2- about the default upmix 2.0 -> 4.0/5.1/7.1 found in the official drivers, I think that it's well done; much better that CMMS-3D used by Creative X-Fi (I have a XtremeMusic). I agree that the lack of an option to enable/disable the upmix is a bad choice made by Asus team. But what I really don't understand is that there's a 'Dolby Pro Logic IIx' technology that supposedly does the same thing, but IMO it's a piece of shit (!). What's the meaning of this? BTW, do you know which cards are affected by this upmix 'issue'?
3- using your mod even with a Xense is still possible to get auto-samplerate just like we can with ASIO Essense ST/STX drivers?
4- how did you change the Rear and Center channel delay?
5- is there a way to change between headphone and speaker output without launching Audio Center? I tried to change using Windows XP x64 audio device properties, but it doesn't work; Xonar Audio Center changes Windows speaker settings, but Windows can't change Xonar settings.
Thanks, man. And sorry for so much writing.
Best regards
Hello,
I did received your e-mail, but was to busy and couldn't respond at that time. I usually respond very fast but sometimes I am very busy and I am overwhelmed with question & support requests comments/emails.
1. Its all documented here in the release notes, I did disable the autostart of Asus Audio Panel & GX
2. Yes DPL IIx does almost the same thing.. Don't know what to say. All card are.
3. Don't know if autosample rate really works, even for EssenCe. If it where to work for Essence it work work for all others. But from my initial testings this doesn;t work and it merely copies the sample rate thats set in Xonar audio center .
4. Complicated question, the delay is a hidden setting, I change the installation files to set the registry settings for the speakers delay to 0;
5. Not that I know of, at least on windows XP,
Hi,
First,thank you for the work in this and help.:)
This isn't so much a problem issue.It's just another regarding DPC latency behavior and the two programs I'm running.
While listening to music using Traktor DJ I've noticed the DPC latency goes up to ~2000+ but, when I load the other program which is G-Force Platinum visualization the DPC latency will go back down to around ~700.
I just can't figure out why?I'm using the low DPC version ,btw.
thanks for any help in this.
Thank you for these drivers! I'm using Xonar Essence STX and Windows 7 x64. I've tried the latest official drivers first and they worked fine except the disappearing sounds in UT2004 when using hardware instead of software emulation. Yours fixed it, but only if the GX option is disabled. That leads me to believe my problem was that I enabled it on the official drivers too, but so far yours are working good (installed with normal mode, because I need the headphone configuration). I'll be checking here for updates! Thanks again.
A simple question: is there any way to save my settings and restore them after a reinstall? (registry or config file)
Check the FAQ section 5. Freshly written:) . Might not save all the settings, cause some of them are stored somewhere in a file or something. When you have the chance to try this. Let me know if it worked 100% or not, and which settings weren't saved.
Do I still need the front panel switch? If so could you fix the link or provide a mirror please.
Yes you still need it if you want to switch to front panel with C-Media Control Panel. Fixed the links, thanks 🙂
Thanks, just to let you know drivers are working fine win7 x64, xonar DG.
Front panel switcher doesnt seem to work for me, any description on how to use it apart from the readme?
It might be a problem with it. My front panel jacks aren't working at all, so I can't check, but you are not the only one reporting it doesn't work.. But there is one more problem, DG has a slightly different system for the front panel and that might be the case. With Uni Xonar normal version, does it work?
Does anyone who tried FrontPanel Switch had problems with it?
Probably GX was at fault, but I think you are way better with the UNi drivers.:)
How is your DPC Latency when your PC is in idle? And when listening in winamp?
Give me some details like what OS do you have? And your system configuration? Your output is set to how many speakers?
I suppose you don't have any other audio options enabled , like Dobly sound.
DPC idles around the 200's.But,it spikes up past 2000 no matter which program I use to listen to music.
The weird thing is, when I load my visualization program DPC goes back down to around 700's???
Audio Channel= 8 Channels,
Sample Rate= 96 KHz,
Analog out= Headphone,
7.1 Virtual Speaker Shifter= checked,
Dolby Headphone= checked.
I'm on Windows 7 Ultimate 64bit.

Thanks
[edit]
I think I might have found something to do with my issue here: http://www.native-instruments.com/knowledge/quest... but, all this is still confusing to me.ha
[2nd edit]
lolz I fixed it,sorry for wasting your time.
I had Traktor DJ set to use Direct Sound instead of ASIO driver.Latency doesn’t go past ~270 now.
Thanks,anyway 🙂
Thats great that you manage to find a fix.
Some tips anyway, might came in hand:
1)Disable HPET timer in the motherboard's Bios. This seems to be the a cause of high DPC latency for Win7 & Vista in some cases.
2)Since you said that by launching visualizations , is actually lowering the DPC latency, this might be because of how windows 7 manages the timer resolution. In some cases the timer remains at its IDLE value and its not changing like it supposed to, and when launching another multimedia applications it changes. There was a weird bug in StarCraft 2 where the timer didn't change and Starcraft 2 was running horrible, but when people launched WoW in background, Starcraft 2 was running fine.
Download the free version of this program , launch it and press Maximum. I not sure if this will improve the DPC latency or not if you disable HPET.
Thanks for tips.Yea, I'm using timer resolution 2.0and it works like a charm.
DPC rarely goes past ~200µs now.Thanks alot!
The front panel headphones switch 3.7 is working for me on my Xonar DG.I don't use the FP because I get static ,though.
Thanks 🙂 I only wish I could do more, but my hands are tight.
It may seem this way, especially as Tian and that other guy are gone from the support forum, not that they where ever useful. But I think Asus are sticking with 1-2 driver releases per year.. I bet they're main problem is how to prevent Uni Xonar drivers from working, as they or C-Media did something to the driver files so they won't work for multiple cards, and thats why some guys can't install the latest versions..
I tried out the question two for window xp OS, it seem like working pretty well..
(I don't have any issue yet..)
Windows XP 32 bit.
Running Steinberg WavLab and Logic Audio Platinum.
Previously using a SCOPE DSP multi-channel sound card with ASIO drivers, which works great.
However, I need a cheaper alternative on a 2nd PC, and thought this consunmer-grade card would work, but having many issues with the ASIO drivers.
Speficially, ASIO out of the box didn't work.
Uni ASIO drivers did to a point - got 2 channels working brilliantly.
But enabling all 8 channels drops the pitch by about an octave with many drop-outs.
Hoping someone might know a solution before I ditch the card and by another (expensive) Sonic-Core card.
Cheers.
After a round of complete un-installs and re-installs of both the original drivers followed by these (excellent) Uni-drivers, I am happy to say that ASIO output to all outputs is now working flawlessly.
After one attempt, I noticed that outputs 3-8 instead of sounding an octave lower were now an octave higher, and I deduce that to be some sort of sample rate issue.
Re-installing a few times seems to have solved that one.
I'm used to having a sample rate control on the ASIO control panel.
Also a way of 'resetting' the ASIO interface manally.
I wonder if that can be worked into future versions of ASIO 1?
PS. Digital Output (optical) still an issue on my Xonar D2X with many dropouts when the machine is running a highish load (e.g. playing a DVD-audio) so I'm only using it for the analogue outputs, which works great.
Interesting, I too have noticed that installing the drivers numerous times can produce different results...At least in some excepts . There is a registry setting BassBasedBLevel which sometimes changes after install to a different value, and it can't be changed manual. Might be this can be the causes of what are you describing. When installing the drivers again you can check the registry to see what value is set for BassBasedBLevel, and if it sounds right or not.
I did try many times to improve or update the Asio 1, but all without success. I will surely continue to try to improve Asio (1 or 2) , but I can't do miracles as I don't have access to the source code, and I have to rely on various workarounds.
About the Digital output, have you tried it with low DPC latency version of the drivers or C-Media Panel to see if it performs the same , meaning with dropouts?
Takes ages to install on Xonar D2 under Win 7 x64, and at the end it errors with "plug in card". Now it's taking ages and ages to uninstall what scraps actually got installed. If you have a D2, avoid these drivers. Or better still, avoid the Xonars (f*cking Asus crap).
Some Win7 users are having problems installing the driver. They get the "driver signature error".. But that doesn't mean that these drivers don't work with D2!!!
I don't mind negative comments, but I mind when they are way of..
In your case , there might be something else, have you uninstalled the previous drivers, followed by a restart and a driver clean with driver sweeper?
My apologies CarvedIns, I didn't mean to imply that your drivers were at fault or that your hard work is not appreciated. My negativity is aimed squarely at those incompetent tossers called Asus.
There's a cause for the not working headphone impendance control in C-Media Panel?
Yes, thats because C-Media Panel doesn't have the headphone impedance option in its settings.
I tried to activate it separately from the C-Media Panel, and didn't work. I am planning to work on this but it does take time, and my Xonar doesn't support headphone impedance at all, so its a little harder for me.
Hi Carved,
just discovered that under Win7 x64 the Xonar Audio Center still shows 1792 after installing the latest UNi. Is it just a minor bug or they're actually 1792? If I install Daniel_k's it shows 1793.
Thanks!
They are 1793 100%, just didn't updated the information file with the newer number, cause I have to do it for all the supported cards.
Ok, just as I guessed...then it's ok. 🙂
Thanks!
I see. You're involved in an ambitious project here. 🙂
Thanks for your reply. About upmix, is this line of 'AsusAudioCenter.dll' the one to change: 'DDL_UPMIX_PROLIIx=1'? Also, I saw a reg file tweak that disables the speaker delay to 0 by changing reg key entries: 'LsRsDelay', 'LbRbDelay' and 'CenterDelay'. But Xense doesn't seem to have these entries after the driver installation. I'll try to play with these reg keys anyway and see what happens.
Thanks again!
That line in the asusaudiocenter.dll is for stereoupmix through SPDIF . For analog I disabled/deleted the registry key "Dual2D" , now that I think about it this is quite simple but it was a real pain till I figured this out.
The delay entries are present in the registry only when changed, and the drivers use by default the 10 and 15 ms.
No problem. If you don't mind I just have to ask why are you interested in this things? 🙂
