Quality of sound from Realtek

Good morning ...
In my last PC I have a sound card from Creative and their cambridge speaker set. The music from that was good. However since i have upgarde to my new machine and using their Realtek sound but with my old cambridge speaker. I noticed that sound cracks when its at high volume and don't sound as crystal clear.
Anyone notices the same problem?

Realtek should be banned from motherboards. There is allway some kindd of trouble with their chips!
Realtek is CHEAP, and thats the only reason MB produsent's buy their products.
Nothing wrong with Realtek codecs, particularly the most recent AC'97 and HD product lines. In fact, Realtek codecs have compared favorably to Creative products in subjective music and DVD movie playback listening tests performed by many review sites. e.g.
The SB Audigy SE generates better gaming audio quality than the Realtek ALC-882 based systems and similar DVD/music audio quality. In our subjective headphone testing we noticed differences between the two codecs, with the output from the ALC-882 sounding cleaner in the mid-range tones with deeper bass in the music and DVD movie playback tests while ambient sounds and positioning in the games tests clearly favored the SB Audigy SE. However, the difference was minor when utilizing our 4, 5.1, or 7.1 speaker setup in a typical room environment. - MSI: SLI Plus Eight, Anandtech.com
Both The Matrix and Dream Theater Live at Budokan took full advantage of our 5.1 surround system, though we preferred listening to Dream Theatre using the higher quality headphones in stereo while watching. And so, we listened both ways on each card just to cover the bases. And what do you know, but we just couldn't find favor with any of these cards. Each did as good of a job as the last playing back these higher quality audio streams. - Winter Audio Reference: On-Board, Consumer, and Pro Solutions, Anandtech.com
There are innumerable ways that motherboard designers/manufacturers can screw-up the analog signal output quality by paying little attention to design, including poor MTRR or chipset optimization in BIOS that results in latency or interference problems (e.g. users reporting "I updated my BIOS and all the crackling/noise/whining went away"). You can't just slap a codec on a board surrounded by dozens of high-frequency signals and expect the codec to compensate or correct for all the short-comings of the board design. Similar complaints can be found with any codecs, including ADI, and even sound cards are not immune to these problems.

No sound from RealTek audio card? [Solved]

I can't hear any sound from my laptop. This is what I executed:
pacman -S alsa-utils
gpasswd -a yourusername audio
alsamixer
aplay /usr/share/sounds/alsa/Front_Center.wav
alsactl store
nano /etc/rc.conf
DAEMONS=(syslog-ng network crond alsa)

If I understand you correctly, you have installed all required alsa packages and tried to configure. What doesn't work is attempting to push up the volume via alsamixer/aumix etc., unmuting also does not work.
Am I correct?
If so, you may have a similar issue to what happened to me a ways back. Is your current kernel up to date? The problem I had involved the fact that my sound card (though it was extremely common and, well, sh*tty) was affected by a feature regression in the ALSA code and an incompatibility with kernel in what was then [current]. I had to wait for the kernel to catch up to ALSA to do anything, but the regression had to be fixed before I could do anything useful.
Moral of the story (also known as the 'tl;dr' or 'too long; didn't read' version) - Try updating your kernel if all else has failed. If nothing useful comes out of that, try searching the ALSA site.

No Sound from Realtek on K8N SLI-FI (NOW FIXED)

New bulid all snapped together well enough but I am getting nothing from the
Realtek AC'97 neither through line out nor front panel.
A souncard when intsalled to check performs as normal.
Without/before the soundcard added everything looks fine. All okay in Device
Manager and no error messages when sounds/music playing nor in speaker
setup... just not a peep from the damn board. BTW I didn't connect a speaker
until late after installing the OS.
I have updated the drivers but not flashed the BIOS, there wouldn't appear
any reason to. I have version 1.2, 1.3 shows nothing relevant so why risk
RMA problems?
UPDATE: FIX = RTFM
I had forgotten about the jumpers on the front panel audi connector. Disconnectiong the front panel and replacing jumpers gives back the sound.
I still have a problem that the front panel audio connector I used is incompatible, but shouldbe able to confirm by cross checking wiring.

FIXED
"MSI reminds you... 5&6,9&10 have to be jumpered."
Possible problem with cases front audio panel/connector but onboard sound okay.

DOS sound from realtek ac97

Hi I have a MS-6524 motherboard with ac97 onboard sound.
I have some legacy DOS games in which I would like to get the sound working - does anbody know how?
TIA
Mike

Running a dos program in w2k. Everything works except that the game (SWOS 96-97) won`t recognise the soundcard I have tried the auto-config for every possible listed card and also tried setting manually to no avail.
I downloaded "dosbox" after doing a search on this forum and finding somebody else had had a similar problem and used this, the sound then works but performance is rubbish.
Any ideas?

K9N Platinum- Only 2 channel sound from SPDIF

Hi Guys,
I am struggling to get a 5.1 output on SPDIF in the Realtek Manager. If i run the 3d sound demo, all i can hear is sound from the front 2 channels, no centre or surrond speakers. This is extremely frustrating. Can someone help ??

Quote from: ivon on 09-August-06, 17:23:28
I am tempted to go and get the Creative card...However one of the reasons why i shelled out money for this Mobo was because of the SPDIF out put ...and i cant get even the Realtek sound manager to out put to the five speakers...
I could have gone in for a cheaper ASUS board and a creative card...however i cant afford another card at this stage mate. Need to figure out a way to get this working.
Where can i get the latest drivers for the 883 chipset.
Jal
STOP!!!!!
Don't just go and buy a Creative card, read these first:

If you want surround sound using spdif (optical or coaxial) the cards from Auzentech is for you. I'm using the HDA Xplosion but I think they are going to release a new card called X-purity in September. Their card can ENCODE Dolby Digital and DTS so you can enjoy surround sound using spdif. To be honest, my card, the Xplosion is not that great for gaming as it uses software+hardware Dolby digital/DTS encoding so you will lose some CPU usage for the card. It'll also cause your system to lock-up sometimes if the driver is corrupted since the encoding relies heavily on the driver. Eventhough it has those problems, I would not trade this card for a Creative card, not until Creative makes a card that will encode either Dolby Digital or DTS. The advantage is you can connect your PC with a home theater system or if you are using a Logitech's digital speaker (Z5450,Z5500) you can use the 3 analog inputs for 3 other device rather than only from PC. Btw the analog output of my Xplosion is also good but not as good as X-Fi, but you can change the opamps to make it better, but it wouldn't change the digital output quality at all.

No sound from HP G62 laptop and can no longer get sound from speakers or headphone jack . USB sworks

have an HP G62 laptop. I can no longer receive sound from speakers or from headphone jack. If I plug speakers into usb - I will get sound. Any ideas?

I don't think I have anything to offer that you haven't done. In Device Manager, Device status says "working properly" and you've reinstalled this driver.

Sound from speakers & headphones is monaural NOT stereo HP Pavilion TS 15 Notebook PC Win 8.1

My HP Pavilion TS 15 Notebook PC is only 2 weeks old I found out soon after I got it that any test I do of the left and right speakers or headphones is not stereo. When I click on the left speaker I hear the sound in the center and when I click on the right speaker I hear the sound in the center. I have tried a test from the internet same results. However, if I connect a bluetooth audio device then when I click on the left speak I hear the sound on the left only and when I click on the right speaker I hear the sound in the in the right only. Also when I boot the computer with Ubuntu 13.10 there is stereo distinct sounds from either the left or right when I run the left right test.
At first and before I installed Ubuntu HP was sure it was a hardware problem and sent a tech out to install a circuit board which the headphone plug was on, thinking the jack was defective and mixing the left and right channels. That didn't fix it. I went to the Realtek website and ran their program which removed all traces of the sound driver and installed the newest one they had, didn't help. Hp log into my computer and cruised around but found nothing wrong. I have played with every sound setting there is, no change. The final solution they suggest is to reinstall Windblows 8.1. I really don't want to do this as I just did it to transfer from my win 7 notebook to this one using windows easy transfer. FYI this computer is one HP sent me to replace the previous G6 Win 7 notebook which had unresolvable problems, worse than that this is the 3rd computer HP has send me to replace previous ones which each had their own set of unresolvable problems. So I haven't had very good luck with HP computers!
Anyway I am left with maybe a couple possibilities. 1. Reload windblows, I cannot use easy transfer because it no longer works on win 8.1 (maybe file history will work though I'm not sure) 2. Try windows refresh which won't remove as much of what I have installed. 3. Maybe someone has experienced a similar problem and can share here.
Any help is appreciated.
Michael
UPDATE:
HP wanted me to do a clean reinstallation of Win 8.1, sent me the disks to do it, but the disks were defective and wouldn't go on to the second disk. I used the Disks I had made from the computer they worked and the reinstallation was completed. That didn't resolve the problem! They decided to send me a replacement computer.
The new computer is a HP ENVY TS 15 Notebook PC with win 8.1 updated. Same problem except the speakers seem to be in stereo but the headphone jack is still mono. I chatted with HP last evening and was told this is a "Known problem and the fault of Windows 8.1" Can someone tell me if this is true? I have doubts but really want to know.
Michael

Hp replaced this computer for me due to this problem, however, the Envy (dumb name) they sent me to replace it had the same problem. I did fine a solution and here is the web address http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio/envy-17-headphones-in-mono-not-stereo/td-p/...
Read down a few posts for the solution by making changes to the registry. But, my problem and the solution was with a win 8.1 computer and I do not know it it applies to Win 7. Unless, you have the same sound card and driver, which I doubt. If you haven't removed the sound card driver and reinstalled it with the one on the HP website do try that.
Good luck.

Difference in sound from A2Z and DVD home equipment

Hi,
Does anybody tell how different in sound from Audigy 2ZS and home theater system. What i mean by this is the output system is the same (Home theater speakers, surround receiver). The only difference is signal source, either from sound Blaster A 2ZS or from home DVD player.
As far as i understand, the A 2ZS wont maximize its utilities if we select the SPDIF pass through and the signal will be sent directly to the external decoder. Am i correct to say this? and if so, the sound quality is totally subject to the external decoder and speakers systems. But i have read couple audiophile forums, it said that the sound varies according to CD/DVD player, how come we have this.
To conclude, any strenghs of A2ZS over home CD/DVD player interms of sound quality?
Appreciate if anybody could tell.

Well sound in this context is made up of 3 componemts: source, amp and speakers. The 3 things to watch are THD (total harmonic distortion), S/N (signal to noise ratio) and Frequency Responce.
For a good system you need <0.0% THD, S/N >20 Db and frequency responce at least as wide as 20 Hz to 20,000 Hz.
There is a difference between listening to music, which is best in stereo, and home theatre, which is designed for spacial effects rather than reproducing high quality music.
To address your question directly it is not possible to answer because you wish to compare a disc player with what in this instance may be described as a switch/router.
In relation to sound between the Audigy 2 ZS and my home theatre system there is a world of difference even though they are interconnected. That may be because of a 25 fold difference in cost though.
Home theatre should include video switching as well, normally incorporated in the amp and called an AV amp. Spend money on a good one of these and you won;t go wrong. Look for 6 powered channels with a minimum power of 30 RMS per channel. In stereo mode the 2 channel amps should be class A. In 5. mode you will not get the above specs unless you are intent on spending serious money.
Hope this is helpful.

Can't record sound from DVD player

I just built a new DAW with a Gigabyte MoBo that has the Realtek sound chip on board. I installed an M-Audio external Fast Track Pro connected to the computer with USB 2.0. With the two sound devices I can play Band in a Box (my main band) through the Realtek and out put to my mixer. I then use my Line 6 Pod XT as a preamp to my guitar that also goes to my Behringer mixer. I connect the main out (R&L) from the mixer to the 1 and 2 inputs on the M-audio. I set Audio Hardware setup in AA3 to use the M Audio device for input and am able to record mixer output to tracks in AA3. I tried several configs and this is the only one that I found that works. All is good so far.
I installed a SATA DVD player (Lite on 24x) that works fine, but it plays through the M-Audio via USB, bypassing the Realtek chip, and the sound does not show up in AA3. I'm thinking I need to route the DVD output to the mixer to use the channel that is already set up. I've been trying to output the DVD player through the onboard Realtek but can't find any way to direct it to do so. I don't necessarily need it to play through the Realtek, but I want to be able to record from the DVD player.
So, does anyone have any idea how to direct the output of the DVD player to the sound card of choice? I'm stumped.

Eric,
Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
I'm trying to record the sound from the DVD not rip the track.
When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing.

No sound from windows 7 on bootcamp

I bought my lovely brand new imac, done all the updates and all is good, I installed windows 7 on bootcamp but cannot not get any sound from the windows, yes I get sound while running the mac but when I boot to windows 7 i hear nothing.
Now the meters that should pop up and down do that so there is sound there I just cant hear it, I have gone without sound for 3 months now and its driving me mad.
I have been to various sites and downloaded high definition drivers etc but still no luck, any ideas?

You need to install your audio driver yourself, which would be RealTek.

My satellite L675D-S7015 all of a sudden, no sound from HDMI

I have a satellite L675D-S7015. It came with HDMI out, blu-ray player and all the bells and whistles. Up till a week ago the only thing I had to do to it was replace the screen after my friends kid broke it. But last week, I lost all sound to my receive. Now I have checked everything I can...made sure it was set to default....in the sound icon and by going through the realtek HD audio mgr. Made sure nothing was muted and all that good stuff. I then went into my device mgr...only to see that my ati HD HDMI driver had been replaced by some generic HDMI sound driver. I've uninstalled this several times and reinstalled the Realtek driver...only to have it replaced again. Is there a way to stop this? or what do i need to do to fix it? the generic HMDI driver will play sound, but I have no control over its settings it seems. And also...I thought that HDMI was more than just stereo? but the realtek HDMI settings, even when I have the box checked for it to allow true dolby d and dts, it doesnt give me any other optin in setup other than a stereo one? am I missing something?

I found this on the Microsoft websiite. (I am assuming you are running a Windows 7 machine)

Very poor sound from internal speakers, very good on headphones.

Hi,
I hope you can give some advice.
New to all this so apologies if protocols are broken etc
New 20" imac, running Leopard.
very thin, tinny sound from internal speakers (similar to hearing someone's else's walkman
on the train). when I plug headphones in its great no probs.
Advice please! I don't want to send it back I'm halfway through my assignment.

I just realized I've never heard the internal speakers on my new iMac, I have always used good 2.1 speakers since I got my eMac years ago and the internals really sucked.
I was just curious, have you heard anybody elses built in iMac speakers and did they sound better than yours or the same? Maybe at the Apple Store?
I don't know, I just didn't know if they really improved them. Maybe other iMac users can chime in on internal speaker quality. The only reason I said all this was because you mentioned that headphones sound great, which is the same port that a set of external speakers would go.
Sorry to hear you had to send it back for that. Here's hoping you didn't have to send it in for what the speakers really do sound like.

How can i import a music CD including all sounds from 5Hz to 30KHz?

In order to be really lossless what configuration must be used?

+"how can i import a music CD including all sounds from 5Hz to 30KHz?"+
+"In order to be really lossless what configuration must be used?"+
That is two different questions. If you want "lossless," which is defined as being sonically equivalent to the source CD, iTunes has 3 choices, as thicks noted.
However, that does not provide frequency content as high as 30 kHz, since normal CD encoding is based on 44/16 PCM, and rolls off well before that. If you want all those frequencies, you have to use studio quality masters based on 192/24 encoding, which is far beyond iTunes's capabilities to handle.

[Solved] No sound from VM (Windows 7) on qemu with virt-manager

I posted this in Newbie corner,
https://bbs.archlinux.org/viewtopic.php?id=176131

Self reply.
Finally, I got to hear sound from windows 7 as guest OS.
I gave up to use virt-manager and launches OS image by command line
like follows.
% export QEMU_AUDIO_DRV=alsa
% qemu-system-x86_64 /mnt/win/win7qemu002 -cpu kvm64,+nx -enable-kvm -m 1536 -soundhw hda -usb
Then, sounds works good.
# However, the quality is bad because of heavy CPU load.
Virt-manager may make things complex..
Sorry for the duplicated post.
