Audio over Displayport

Heya,

i'm currently playing around with my first thinkpad ever, the T410 with integrated intel graphics. now i found the first big problem: i can't get audio through displayport. i got a dp/hdmi adapter which should be able to carry the audio signal. there's "intel display audio" together with a "connexant 20585 SmartAudio HD" in the systems tab, but i can't manage to get the intel as default device :/

has someone got audio with displayport and integrated graphics working?

ps: sorry for the bad englisch

 

Did you set the audio device under Playback Devices to DP?

 

currently the only t410 that has working audio over displayport is the one with discrete video, not integrated

hopefully lenovo will fix it in the future, but right now you are out of luck

you can read about it here: http://lnv.lithium.com/t5/T400-T500...3;jsessionid=C919814B57268F9CE38E719AC2230364

 

hrmpf. so i'm from hooray thinkpad to i hate lenovo. damn that i can't return that thing to get an other laptop. thanks for the help and shame on you lenovo! kohut said it's working on those machines!

 

Are you 100% sure? I got my DP->HDMI adapter delivered today and I just tried it out with my T510 with integrated graphics, attached via HDMI to my TV, and I was able to get audio over HDMI, though my TV speakers. At first the audio came by default out of my laptop speakers, but I went into the Sound control panel, and it listed my TV, and I set it as default.

According to ThinkVantage System Update, I have v 8.15.10.2008 of the Intel HD Graphics Driver.

 

Hey Mutnat,

this is really great news for me. Searched the night for someone who could show me a nv-t410 (really need audio). i just have two questions: could you please do a quickstep guide? (just 2-3 pictures of the screens of what it should look when it's working) and which adapter do you have?

many many thanks in advance
andreas

 

Yeah I'll try to remember to put something together tonight or in the next couple of days anyway.

 

Oh and I'm using this adapter from Dell: http://accessories.dell.com/sna/products/Cables/productdetail.aspx?c=ca&l=en&cs=cadhs1&sku=330-1271

 

Has anybody had any luck getting audio through DP on the X200T & X201T with ultrabay?

 

There's no display port on the x200t/x201t, only VGA. You'd have to buy one of those stereo cables, plug it into the headphone port, and the other end to your tv/stereo equipment/what-have-you.

Thanks for the link mutnat! I will order one, just in case for the future.

 

the X200/X201 s and t variants have displayport on the ultrabase and not on the laptop itself.

I know the X200 variants don't have audio support, not sure about the X201 variants.

 

Here is your answer from the X201 owners' thread: yes, it works.

 

Oh I'm sorry, I didn't think he was asking about the ultrabay.

 

He was not -- I think he was asking about the Ultra base (but made a typo in his post).

 

That's what I meant, ultrabase. Gahh. :laugh:

 

Oops. You're quite right!

I'm glad y'all were able to understand that which was lost in translation from brain to keyboard.

 

hey, thanks mutnat. searched for the dell adapter... they want 40 euros for that in europe. but i'm happy that this is going to work with the right adapter

 

Hey guys sorry I didn't get a chance to write up anything last night--I was just too tired after dinner and ended up falling asleep on the couch. I hate that. But yeah it wasn't rocket science. Basically what I remember is I plugged in the cable, switched my TV to the correct HDMI input, and then hit I think Fn+F7 on the keyboard to bring up the external display modes and picked extended desktop or something like that. At first all I got was snow, but then I went into the Display control panel and tweaked the resolution and all of a sudden it was working for video, but initially audio was still coming out my laptop speakers. A quick trip to the Sound control panel showed both my internal sound and my Samsung TV as options, and I set the TV as the default device, and voila I had audio out the TV instead of the laptop.
