    Question Realtek ALC892 Opinions?


    What's the general consensus on the Realtek ALC892 audio chip that's found on some ASUS m/b's? I'm considering options as part of my due diligence in pricing out a possible new PC build. I use the PC for listening to music, and may do some audio editing and/or mixing. I don't do much in the way of recording or capture, at least for now.

    I do have a camcorder and Adobe Premier Elements, but I haven't really gotten into that to any extent. I'm not sure if this involves the soundcard/chip to any degree or not. There doesn't seem to be much in the way of reviews available on the Realtek ALC892, except for a few lines in m/b reviews.

    Eagerly awaiting your wisdom! Thanks . . .

    I don't have any problems with it. I think it's pretty good actually. My last mobo had the same chipset, but for some reason my current mobo sounds a bit cleaner. While I haven't put it up against any real competition, it makes me question those who believe general use sound cards would be an upgrade.

    Unless you have specific needs or the equipment and speakers to take advantage of a high-end card, I really don't think you need to consider anything else. It's kind of like the difference between a 320kbps mp3 and the actual CD. One is superior, but most can't hear the difference. Your own preferences would come into play at this point.

    This discussion, though not specific to the Realtek, covers some of the pros/cons of using onboard audio:

    My Asus P8Z68V Pro uses the ALC892 chipset, and I think it sounds very good. Im a big audiophool/junkie and its definitely something I could live with everyday, no intentions to upgrade.

    Might be a little late now, but I just got my P8Z77-v-Deluxe board today, and it has it. Got to say it's really clear. Much better than my old motherboards onboard audio.

    That pretty much makes up my mind, thanks!

    I'm thinking about the ASUS P8Z77-M and an I5-3570K. Right now I have the system below, and have to replace the m/b because it decided to quit. I have a warranty replacement, and just have to get in gear and actually do the deed.

    I was planning to wait for another year, but any excuse to upgrade and I start plotting. I can usually justify things by saying I'm giving the old set-up to my brother. He hasn't had to buy a computer in well over a decade. Lucky him!

    ALC 892. It Sucks!

    Quote Originally Posted by JohnnyCNote View Post

    It shouldn't, really!. I have a new Asus 990x EVO board with Realtek alc 892, the sound chip inside is pretty much separated from the rest, so interference is at a minimum, it has 6 (!) connectors, a fancy software to control the chip. So its great! Or is it?
    Well, ...it's not.
    How do I put it, I used to have an old Genius live maker 5.1 PCi board ( or they could have named it just as well: The crapiest dedicated sound card in the world). And since it doesnt work with windows 8, Im stuck with the onboard chip. Which, again, sucks.
    why it sucks:
    1. The connectors are not configurable.
    2. The sound from the rear speakers its like coming from inside a frying pan.
    3. The Dac convertor makes my mp3's sound like a Transformers movie.
    Whoever says buying a dedicated soundboard isnt worth it, doesn't know what he's talking about.
    I have microlab active speakers 48W, Pioneer Amplifier, and Pioneer passive speakers 120W.

    2 year old thread....

    This old Realtek codec isn't as good as the new ALC1150 one, that is for sure. The 1150 sounds pretty good for the majority of people. Its not until you get into a good set of cans/speakers/setup that most would want to move to a discrete card. And that discrete card should be good to improve upon the ALC1150 codec.

    You don't have a clue. I have the 1150 and it is nice (funny enough I have never heard it without the dac). I still have it connected to a 24 bit dac via a toslink cable to my 50w (peak 75) A5+'s (speakers are excellent, btw). As for the op's question, for normal listening, as long as you have decent speakers (thd <=0.05%), you will be fine. If not, get better speakers to begin with. Then if you get any static or feedback from the mobo, at all, or if the connections are not to your liking, get a nice soundcard, and I don't mean Creative. Asus Xonar or m-audio type.

    Large amplifiers as well as large power supplies (ie 1000w+) work better and cleaner with smaller loads was what I was referring to. If your speakers don't have a clean thd, none of that matters. Which is why I will never buy a stereo amp unless it has extremely low thd, speakers included. Onko does a nice job for not a lot of money. I run my pc, my monitor and now my speakers through my ups not only to negate power outage hiccups, but as well just to make sure there is no line fluctuation. My audio setup cost me half what my entire pc cost, sans monitor. Plus my music is almost entirely in flac. Peace

    One of the big problems with mainstream audio amplifiers is that their wattage is "marketing derived", meaning it could be as little as a few seconds at indicated power. The output inductors and PSU magnetics are often where the corners get cut and those also contribute to the amplifier running hot at idle due to increased core and switching losses. (Hence why a good amplifier should not run hot with nothing playing, except tube amps of course.) Surface mount MOSFETs and HVICs have less of a problem as their higher operating frequencies mean there's less reason to cost cut on the output inductors, but the issue of them cutting corners on the PSU are just as bad as before. Variable supply rails also helps a lot (lower supply rails = lower losses) and boosts dynamic range.

    It's too bad that DIYing a purely digital amplifier from scratch is very difficult to do even for an experienced electrical engineer. There aren't even very many modules that accept S/PDIF directly and no easy way to break out HDMI audio into a bunch of I2S or S/PDIF to drive all the channels.

    It seems like a lot of audio amplifier designers don't know how to design good power electronics. (Such as my old Philips digital amplifier that had an awful lot of cross conduction - it ran hot with nothing playing and put out loads of EMI!) I would like to see a big power electronics manufacturer like Delta or ABB get into the audio amplifier market. Based on my experience with their power electronics products, they could pretty easily build a true 1500W amplifier smaller than a shoebox.

    I think one big reason why most digital amplifiers don't shut off the PWM with no input signal is because they use the same PSU converter for the output stage and the logic, so shutting off the PWM will cause a big cross load condition. That's also another reason to go for variable supply rails since that almost always means a separate converter for the power stage and the output stage on most of those do shut off with no signal. (An easy way to tell is to see if it runs warmer with the volume turned up while playing a silent track.)

    Let's keep our dissertations focused on helping the OP.

    If you want to discuss the merits of amplification, start another thread.

    In summary, as long as you're using a digital amplifier, any modern onboard is as good as any other. The reason being that digital audio is just data. If you use HDMI, the onboard codec doesn't even do anything.

    All this was because of a thread necro. The OP hasn't been here in two years, when the original thread started.

    I have the OP's audio chip and find it "ok". I have no way to verify any mp3 vs CD sound analogies because I don't have any mp3 files. If I really want decent sound I burn a CD and use my CD player to play it. My PC and CD player go through the same amp and speakers so it is an apples/apples comparison. I have discovered that a sound card isn't going to improve on my CD player's audio quality so I haven't bothered.

    If it's a digital amplifier, the sound card should have no effect at all as it's just data. Good sound cards are really for use with headphones and/or tube amps.
