Well, here's another drivers to try:
Realtek High Definition Audio Driver for Microsoft Windows 7 (32-bit, 64-bit) - IdeaPad Z570 - Lenovo Support (US)
That's for a laptop but then again, if the inf file has your hardware ID on the list, it should work without problems. Hopefully this will be the solution or else you need to get a Digital to analog Converter (i.e. external soundcard) with SPDIF input to get sound out of your speakers.
Nothing happend,i dont know what is the problem,really.It was always working fine,i never used that external soundcard.Maybe my soundcard isn't working,how can i check that?
The device should say something like Code 10 or Code 43. Can you see if shows any error on Device Manager?
It says
Device status
This device is working properly.
Try reinstalling the drivers by making sure to delete the driver software:
Tried still nothing,ill try external soundcard than Ill see what will happen.
Anyways, it's still baffling that you can't install realtek drivers even though the soundcard is actually realtek HD audio per hardware ID. It's also astonishing that you can't select speakers as default device despite device manager showing that the device is 100% functioning.
External soundcards tend to be expensive as they're usually sold to audio enthusiasts who are willing to pay ridiculous price to gain a subjectively improved sound. You'll probably be surprised by how much they cost considering that they only convert digital to analog sound. External soundcards are mostly plug-n-play so you won't need to download drivers at all. Just make sure to set the default device to Digital Audio (USB) and plug your speakers to the 3.5mm jack on the soundcard.
If you want to spend the least amount of money in external sound cards and don't need to get a Hi-Fi USB sound card (more commonly known as DAC by audio enthusiasts), I suggest to buy Syba SD-CM-UAUD USB Stereo Audio Adapter which is the cheapest that I can find. Also, don't get confused with a headphone amp and a USB DAC as headphone amp only amplifies the volume output of the soundcard while a USB DAC is essentially an external sound card.
My brother is a musician,he has external soundcard so I will try his soundcard when he gets it from his friend.I hope that it will work.I cant see the other solution,maybe my soundcard isnt dead,maybe it is just a green conector for speakers that died? Could that be a problem,what do you think?
I'm guessing that the amplifier on the built-in sound card is broken which is probably why you can't set speakers as the default audio. If the DAC chip is the one that broke, Windows would've shown a code 43 error or code 10. I've never experienced a dying onboard soundcard so I have no clue.
I know this thread is old but I had this problem the other day. I realized one of the 'Digital Audio (S/PDIF)' was set to default and the "Speakers" choice was not even showing. What I had to do was go into Control Panel. In search button top right type in troubleshooting. Click Hardware and Sound. Then choose 'playing audio'. Just follow the prompts and it should find that your speakers need to be set as default. Then the 'Speaker' under audio devices will be back as shown in pic below.
