I got myself an audigy 2 zs today. Installed it everything went smooth. Only problem I have is when ever I play that sample 24 bit file they have in that welcome screen. The sound crackles, screeches and then returns to normal then 2 seconds later does the same thing. My speakers are the inspire 5.1 digital 5700. I also have win DVD. and in win DVD's setup menu. i have the option for analog sound card and digital SPDIF out to external processor. I f I pick digital SPDIF and pick the enable 96 KHz/ 24 Bit decoding. I get that screeching sound like the sample audio file. What can i do to fix this and could it be the card thatís bad? Or maybe the receiver for the speakers?

Also under device control-AudioHQ should I put my digital output sampling rate at 96 or 48 KHz? And an explanation on this stuff would help too. Finally in the decoder tab I have the option of use installed decoder or SPDIF PASSTHROUGH. What do you guys think I should use? Any help would be appreciated.

first off very nice speakers! it took me a while to track some down myself but i finally got them! :)

anyway.......

have you tried updating the drivers for the sound card? goto
http://uk.europe.creative.com/support/downloads/su.asp
it should automaticly download and update the driver for you.
also i used to have this problem with my audigy 1 sound card, tried updating the chipset drivers for your motherboard? if you dont know where to get them post your system details

I would use the spdif passthough, the decoder on the inspire digital 5700 is actually very good.

Sampling rate means how many 'samples' of music should the audio card pass on to the decoder. The more the better. Basicly we are dealing with a digital sound (lots of 1's and 0's) and with digital you can not excatly represent the analogue audio signal. so this signal is then 'sampled' at seperate points in time and the value is converted to digital. the more samples you have the better you can represent the audio. Also the amount of bits used to represent a sample affects how well the system can represent the original audio signal, the more the better but any normal person can not distiush more than 24bit quality.

i hope that makes sense

as far as drivers i figured as much. so thats the first thing i did. i updated my mobo drivers i got a asus nforce 2 board ( A7N8X-E Deluxe) and i ran the auto update thing for the soundcard and that went fine. no errors or system crashes. I am running my speakers through digital output and just found out (by reading the manual) that DVD audio is only allowed on analog. I've also noticed that almost every program uses the card instead of tossing the work on the 5700 reciever. If the card does all the converting for you then what would be the reason to toss down extra cash on a inspire 5700 (digital). That kinda makes no sence. I'm gonna continue my troubleshooting please let me know what you think about what i've written. also i've performed a clean boot and still same problem. Thanks for all the help.

what motherboard do you have?
have you tried flash updating the bios?
theres a setting the bios which may help, but my mind has gone blank at the moment, i will look it up next time i get a chance....
can you test the card in a different machine? to eliminate software/hardware incompatablities

also in the cas of the 5700 i use a hardware mpeg decoder for dvd playback which pass's a dolby digital signal to the reciever, also the system gets very high reviews considering that you can spend 2 to 3 times more on a system and get similar results, personally i'm very happy with it :)
esp. since its got a digital DIN input which is required for an audigy one card.

the bios is updated. i did it no to long ago as far as the feature you're telling me about in the bios if you come across it let me know. I was wondering if i connected my reciever to the analog inputs. would it make any difference. I don't watch any movies on my computer, i mostly listen to music and play games. i rather put the card to work and let it assign where audio goes rather than this digital output doing it. also i would be able to play dvd audio. Let me know what you think?

I'm gonna keep it digital but as far as this sound problem goes. i'm guessing it's driver related. everything on my computer is up to date driver wise. i could try going to an old board driver but i don't know what do u guys think? The only thing left to do is reinstall the card and try it on another system. And i don't think that will do it either. But most my firends hate creative so it's gonna be a pain for me to get them to do it. Any other ideas are welcomed. I got the dolby digital to work on dvd's. had to enable the passthrough on winDVD and the device settings in Audio HQ. So far i've noticed that when i put use installed decoder in the audio HQ (device controls) my audio works fine except for any dolby digital dts, pro logic, 24 bit files. (before if i play a movie and put it to play in dolby digital mode on the reciever it would get distorted like the 24 bit audio files. but with the spdif passthrough enabled the reciever takes care of it with no problems. i also ran that showcase demenstration and nothing worked except for the EAX HD. DVD Audio was distorted like a explained before. and when i sampled the THX stuff, Dolby Digital EX and DTS ES i got the same distortion. I guess it looks like i'm gonna be waiting for new drivers. Should i call creative and report this???

the bios settings i was thinking of where
pci delay transaction
and
pci ide busmaster (i know it says ide but it makes a difference (sometimes))

can you post your system specs, including
mobo make/model
gfx
ram (amount and type)
windows version

also make sure ALL drivers are upto date not just the audio and chipset ones

MOBO = ASUS A7N8X-E Deluxe
Gfx CARD = GeForce 6800 GT w/ 256 mb DDR2
RAM = 1 Gig (2 X 512MBs) Crucial Ram PC-3200
OS = Windows XP PRO

Iím gonna check those settings hopefully by tomorrow. Iím Downloading a 3 gig file so itís gonna take a bit to complete. The only driver not up to date is my Gfx card. Which Iíve downloaded and I am waiting to complete the 3 gig download then Iíll install, reboot, go into bios and find that setting. Iíll post my findings and results. Thanks for all ur help Jake.

Ok everything up to date and still same problem. I'm out of ideas. still trying to convince a friend to let me put the card in their system. but this seems to me to be a driver issue. oh. and those options PCI delay transaction and PCI busmaster don't exist in the bios settings checked 2 times. Should i report this incompatability to creative???? And are u out of ideas Jake? cause i sure am. I've even moved the card to a different pci slot. and still got the sound problem. I look forward to ur reply.

go to run, then type dxdiag.

now go to sound options and drop the hardware acceleration to zero. Check if the problem persists.. if not then increase the acceleration in steps until the problem reappears.. drop it one below this. Ur good to go.

well at the moment i'm out of ideas, but a quick google search revealed

http://www.ocforums.com/archive/index.php/t-349151.html

they are mainly talking about drivers but someone mentions adding a heatsink to the audigy chip and the southbrigde, it shouldnt really come to that if you have good air circulation in the system.

good luck, and if you do find a solution post back so we can easily help out others :)

i'm just breifly looking over this, but if you go into the master volume control program by Creative.
you can turn the master volume down, this sometimes causes too much distortion because of the over amplified signal voltage (you should notice a change at about half volume, then play a sample to hear).
i have a couple other tricks but i'd have to be at my computer to remember what all is involved.
currently i have an audigy card but no computer, hahaha.

once you notice the distortion to leave, you keep the master volume by Creative control panel at that setting, and control the volume instead by the windows volume control.

The auto jack sensing feature can make popping noises, I had to turn mine off because of that.

The thing you were talking about on the 5700 reciever's hardware decoder is for someone that doesnt already have a digital decoder. so all you have to do is choose if you want the card to decode and send it straight to your system, or let the reciever decode.

if you direct the digital feed to your 5700 to decode, that will probably save your system some free resources.

personally, i just pluged the SPDIF undecoded straight into my SONY STR home reciever and let the reciever do all the decoding. straight to my floor speakers, yeah baby!

by definition the optical output would be encoded, using which algorithm (sp?) i'm not sure but the 5700 decoder will auto select the right decode methode.
personally i'm using the digital din input which sounds quite good, do you have this option with the audigy 2?

see this whole problem is only with twenty four bit files. everything else is fine.it seems to be a driver issue. hey jake which decoder is better the receiver or the cards? could the ram be causing the problem???

i'm not sure about the specs of the decoder on the audigy 2, but i would use the decoder on the 5700 reciever for the reasons mentioned earlier. less work for the pc to do yeilds in greater performance. but not much seeing as the audigy 2 probaliy does it all in hardware anyway. when it comes to quality its a case of which one do you prefer?
if i where you i would contact creative about it, many people on this forum may disagree but i've had nothing but good experiance with the tech support staff.
btw i've never phoned them i've emailed them which may have something to with it......

have you adjusted the master volume from the creative control panel?

quality above 24bit may not carry much distortion, or is recorded at a better quality sample. so any distortion above 24bit may not be audible to the average human ear, atleast that is from my experience.

low quality sample on a lower quality sound device may not pick up distortion, and you'll never know that it was there
which is why sometimes you can hear crackling and poping from low quality samples while listening on a high quality sound device, because it has a wider quality spectrum.

so with that said, when the sample playback is amplified, you're more likely to hear the distortion.
if it wasnt the playback sample, then it would be comming from the amplified signal quality.


these are my experiences in general with sound and what not.
but i dont usually have many problems with sound devices.
