Just got Radeon 3450 HD... Can't get HDMI sound working

Well.. what you are missing is that the dvi-connector is unable to carry sound.
If i understood you correctly you are using dvi on one end and hdmi on the other. DVI is video-information only so no dice on the sound.

Actually, the ATI cards can carry HDMI sound and require a special DVI to HDMI adapter made by ATI (which soulstar has). This is why Windows detects the Digital Output Device (HDMI). So, this should work.

Soulstar - take a look at the "audio related" section on the HD 2x00 thread:

http://www.avsforum.com/avs-vb/showthread.php?t=872538

There are some things you can try there.

I have the same problem. Do I need the DVI/HDMI dongle in order to have sound, currently I have HDMI to DVI cable from monoprice which says it supports audio in the specs area, but there is no sound coming out...

Just curious if anyone got this going. There is another thread here for people who were ordering the ATI adapter. (myself included). Mine hasn't come in yet, so I'm wondering if I wasted the money or whether this will work.

Be very careful when ordering your ATI cards. It seems to me, from cruising Newegg, that the package contents on some ATI partner cards don't specifically call out the DVI to HDMI adapter, nor do they show up in the package shots that Newegg does for each product. Newegg should be commended for their attention to detail, and I highly recommend that you purchase ATI cards from them and MAKE SURE from either the product description or product pictures that the adapter is there.

Disclaimer: I am in NO WAY associated with Newegg - just a loyal customer for longer than I can remember.

or just buy the adapter from shop.ati.com for $7 and if you use the code

it will discount it 5% plus give you free shipping.

I bought one, and I don't even have a 3450/3650 yet! That way, I don't have to worry about paying $20 more for a card that comes with the adapter!

Correct me if I am wrong but if you are running HDMI out from a video card to a receiver in order to get sound from the HDMI the receiver would have to have built in HD audio decoders. Since most standalone players have the decoders themselves a lot of HDMI receivers will not, they will just have the ability to play the decoded audio.

So maybe you can't get sound because your receiver can't decode it?

The card sends multiple LPCM channels. All HDMI receivers that decode audio can handle that. Only a few, like the current Onkyo lineup, can actually handle an HD Bitstream.

Are you sure the 3450 sends multiple LPCM channels? I though it was basically SPDIF over the HDMI ports. It's not until the next gen cards until ATI will do HD audio.

Found this in a newegg review, sounds like it might be the ticket for you:

Downloaded/installed latest Cat drivers (8.2) from Ati's site and still had an unknown device upon reboot. Turns out device is an on-card HD Audio chip.

The offical Cat driver package doesn't include the driver for this device. The driver disc that Sapphire packs with the card contains the driver.

You can get a more up-to-date driver by going to Realtek's site: http://www.realtek.com.tw/downloads/...&GetDown=false Its the driver named ATI HDMI audio device listed at the bottom.

Can I enable the HDMI audio and the motherboard audio at the same time? I am curious as there are times that I will want to play video from the hard drive over HDMI in my theater, but play music through the whole house system from the motherboard analog outputs. Can both work simultaneously?

Thanks for all the great info.

I can't get the HDMI sound working either. I am using a single link DVI to HDMI cable. I wouldn't think the "special" ATI adapter is required....I mean shouldn't this be standardized

I have installed the latest driver for the ATI HDMI sound from Realtek's site (1.89) ....but still no go.

I wold be curious to know if anybody has this working and if so what driver, and cable combination are you using? is the ATI DVI-HDMI adapter a must?

Thanks,

I purchased a Diamond Radeon ATI HD 3450. It has a built in HDMI connector. I'm also having trouble getting sound. I tried for 4 days (ATI/Diamond support only open when I'm at work so that was a little frustrating). Diamond tech support says it should pass the 5.1 through so I've sent it back to Newegg for replacement. Video worked fine with setting my monitor at 1440 x 1900 and my Dlp at 1928 x 1080. Netflix steamed to the TV just as I hoped. However without sound it doesn't matter. I should have a replacement card back late next week. Has anyone else tried this card and have you had any sucess with video and sound?

From the sounds of it, some people have HDMI out working with the Sapphire card as noted here http://www.newegg.com/Product/Produc...82E16814102731

but you need to use the grey sapphire adapter, not the ATI adapter

I have a ATI 3650 and have followed this thread and still cannot get the sound to work. Even after installing the Realtek HDMI driver, the audio device does not show up as an option to pick.

Any advise is appreciated.

I am pretty sure you have to get a card....with the actual HDMI output on the card.
You have to plug a digital connector from your "onboard sound" motherboard ...or your sound card if you are using one....to a connector on your videocard "inside your case".

But this will only wrk if your videocard has a HDMI connector built on it.....will not work with a DVI ti HDMI adapter.

I have a DVI to HDMI adapter on my HTPC....and i use a coaxial digital out to my reciever.

Kowal, what you are describing is true only for the Nvidia cards. The ATI cards have an HDMI sound chip on the card, and can effectively act as a replacement for a sound card. There is no need to use a S/PDIF cable between your motherboard (or sound card) and the ATI HD 2x00/3x00 video cards.

Yes, the adapter is going to be a must, because DVI does not normally carry audio. Therefore, a "normal" DVI-HDMI cable is not going to have any of the DVI pins tied into the HDMI audio pins; DVI-HDMI is normally a video-only deal, outside the context of the 3X50/3X70 cards discussed here.

I remember reading somewhere that the adapter from ATI doesn't work with this card but there's an adapter made my sapphire that will.

I'm pretty sure this is what you need : http://www.newegg.com/Product/Produc...82E16814999009

Also, have you tried both DVI ports? Here's a quote from one of the newegg reviewers of this card-
"You need the correct HDMI-DVI adapter (gray color one from Sapphire). But the audio chip is only connected to ONE DVI out. So you only have audio to one device. ATI Catalyst Control Center (driver) version is absolutely necessary for this card. It fixed many many issues with this card."

I have the Gecube HD3450 with HDMI out (no adapter needed). No sound output. I have installed the Ati rear audio output, selected it as default playback but no sound. What type of audio does it need , PCM? I send the feed to the TV input.

Question for you guys with the 3450: can you connect the card to the TV using HDMI, disable the onboard sound driver and still get PowerDVD to output 5.1 via the motherboard's SPDIF connection?

I have the 3450 from diamond also and cant get the hdmi audio working. It works with their crappy driver on the install cd but that wont let me select 1080p for my tv. If I install the newest catalyst 8.3 i can get 1080p video but lose the audio. Any help would be greatly appreciated. BTW I tried the realtek driver and it is even worse because it changes windows into stating no audio device found

if by multiple you mean 2 then yes the ATI video cards will do that. If you mean more than two channels of PCM then currently no add on "Video" card supports that. You can by motherboards that support it and there should be an add on audio card from Auzentech that will support it.

You will only get standard DD, DTS, or 2 channel PCM out of an ATI audio card. My ATI 3850 works perfectly that way. I can't wait to get my Auztench HDMI card in May though. HD audio is what I am really after!

What I have noticed is with the diamond drivers that the card ships with it says the display adapter is a rv620, and powerstrip states the default driver wont even support 1080p. Now If I load up the new catalyst drivers the display adapter changes to the correct 3400 series but I lose the audio. I put in a trouble ticket with diamond support to see what they have to say. I also noticed that when the new drivers are installed if I unplug and replug the hdmi cable the ati warning pops up saying dvd -> hdmi cable appeared (even though I am using a normal hdmi cable), and it says this will not allow sound to be output. Odd thing is this diamond card has a hdmi slot on it so I am not even using an adapter at all. Seems like a driver issue to me.

On a happier note last night I tried a 1080p trailer from apples site and got around 15% cpu usage on my e2180 runnig at a stock 2ghz, so I guess the hd offloading to the gfx card was working Couldnt hear a damn thing though haha...

Me again. I installed windows vista ultimate and same issue. Diamond drivers = sound but 1080i video. Ati drivers = no sound but 1080p. I tried calling diamond on the phone but all I got was a recording and still no reply to my ticket in their helpdek.

Ok I got it working finally! 1080P and hdmi audio! I uninstalled the 8.3 drivers and catalyst package, installed the 8.2 display driver only, rebooted and now I have 1080P and hdmi audio So now I am guessing it is an issue with the 8.3 drivers from ati. Ill look for a place on their site to submit a bug report but for now I'm rockin' 1080p and hdmi audio.

OK I submitted a bug report on their site. I am happy I got this worked out and hopefully the fix will work for others until ati can release an official bug fix The actual driver I installed for vista was named: 8-2_vista32_dd_58133

I have a Radeon HD 3450 from Vision Tek. I am running Vista Ultimate 32 bit. The only version I have been able to get ANY audio out of is 8.2. The audio works when plugged directly into my TV. Unfortunately, when I plug it into my Denon AVR-1909 I have no audio. Is anyone else having a similar issue or have the same receiver with or without HDMI audio?

I have given up on HDMI for the HD 3450. It does not work! I did get sound out of it with older drivers but there were other issues. Newer ones seemed to have abandoned this card. I'm using an XUGA VGA cable with resolution set to 1920 x 1080 x 32 bit color at 60 Hz (1080p) and PC line out sound to the LG 42" 1080p TV. Great picture. Good stereo sound. And no HDMI disconnects. I only use the PC for media center HD OTA recordings. Works great. Pany BD player hooks to LG TV via HDMI the Toslink to Sony AV receiver for great sound for movies.
I currently exploring the nV EVGA GF 9400 GT. I tried the Radeon HD 4550. It had video stutter problems. The 9400 is in my "productivity system" right now. Great pic for MC recordings. Samy 24" 1920 x 1200 moniitor. Working on S/PDIF connector for digital sound. Will test with JG TV when I get it working. For "prod sys", line out sound to amplified speakers is fine.
Trust me, more of the cards I have tried have some kind of issues. I'm crossing my fingers for the 9400. Pic is great. But it is great on the HD 3450 too. That is the ONLY ATI Radean card I've been satisfied for MC 1080i network primetime HD recordings. HDMI sound forget it. HDMI pic? Yes it works. But I get disconnects all the time.
Good luck with your HD 3450.
