Realtek Alc1220 Audio Codec Review
Audio CODEC is the ALC1220 from Realtek with an added N5532 amp to the left. Nuvoton 6796D has been brought in to handle Super I/O. The Killer E3100G can be found on the back of the board. 7.1 CH HD Audio (Realtek ALC1220 Audio Codec), Nahimic Audio - 6 SATA3, 1 Hyper M.2 (PCIe Gen4 x4), 1 M.2 (PCIe Gen3 x2 & SATA3) - 2 USB 3.2 Gen2 (Rear Type A+C), 5 USB 3.2 Gen1 (2 Front, 2 Rear, 1 Front Type-C) - Dragon 2.5G LAN This package contains the files needed for installing the Audio driver. SupremeFX S1220A High Definition Audio CODEC. Asus custom 1220 codec. Realtek ALC1220. Realteks current highest end audio codec. Problem is even with a high end audio codec you can have poor audio if the manufacturer doesn't properly shield or uses poor components. Or you can have a old lower end codec that punches well above its price range. Realtek’s ALC1200 HD audio codec is a SoC and energy-saving 110 dB SNR multi-channel audio codec with lossless DRM that protects pre-recorded and lossless content for full DVD Audio and Blu-ray DVD or HD DVD disc playback. Realtek Alc1220 Vs Realtek Alc892 Realtek Alc1220 Audio Codec Review Do I still need a separate sound card to get better audio for music and games. Search Forums; Recent Posts. I was going to ask the the Forum how good the Realtek ALC1220 is.
Audio codec is a small chip measuring 0.25 x 0.25 inches (7 x 7 mm) located on the motherboard in charge of the analog audio functions. Knowing the specs of a codec will permit you to compare the audio quality of different motherboards, allowing you to choose the right product for your needs.
For further details on audio codecs, including an explanation of the specs we are publishing, please read our tutorial “How On-Board Audio Works.”
We will separate the codecs according to the manufacturer.
Analog Devices (ADI/SoundMax)
Analog Devices are also known as ADI or SoundMax, and their codecs use names starting with “AD.” In Figure 1, you can see an example of an Analog Devices codec.

[nextpage title=”Realtek (ALC, Avance Logic)”]
Realtek is probably today’s most popular audio codec manufacturer. Old codecs from Realtek can be found marked as “Avance Logic,” and both old and new codecs use model names starting with “ALC.” In Figure 2, you can see an example of a Realtek codec.

[nextpage title=”C-Media (CMI)”]
C-Media used to be very popular, especially on low-end motherboards, and they manufactured both codecs and complete audio controllers. Audio controllers usually need an external codec to do the analog-to-digital and digital-to-analog conversions, but C-Media’s low-end audio controllers have a codec embedded inside the chip, which is why we will include them in the table below. Because of that, we included a column called “type” to let you know if the chip is just a codec requiring an external controller (e.g., connected to the south bridge chip) or if it is a complete controller with an embedded codec (usually connected to the PCI bus). Chips from C-Media use names starting with the letters “CMI,” as you can see on the example shown in Figure 3.

[nextpage title=”VIA (VT)”]
VIA manufactures both codecs and complete audio controllers. Their controllers (Envy24 series and Tremor) require an external codec, and usually, the motherboard manufacturer that chooses to use a VIA external controller also picks a VIA codec. Since VIA audio controllers got some popularity in the past, we are including their main specs on a separate table. VIA uses names starting with “VT” for their codecs.

[nextpage title=”Other Manufacturers”]
There are some other audio codec manufacturers, but codecs from them are rarely seen on motherboards. A good example is Cirrus Logic, a company that manufactures very high-end codecs used mainly by home theater receivers. One of their codecs, CS4382, was used on a few very high-end motherboards from MSI (K8N Diamond Plus and K9N Diamond Plus, for example), providing a state-of-the-art audio quality for these products (signal-to-noise ratio of 114 dB). In the past, they also provided low-end audio codecs and controllers using the brand “Crystal.” Cirrus Logic and Crystal products start with the letters “CS.”

Another popular controller/codec manufacturer from the past was ESS, which had chips starting with the letters “ES.”
