Yoga 720 13 audio jack detects headphone on first plug only

My Yoga 720 13 will only detect any of my headphone on first plug, i got sounds and the laptop speakers remained inactive. but after unplugging it and plugging it back no sound came out of my headphone and laptop speakers remained inactive like first time plugged.

 

it seemed my laptop detected the headphone on the second plug but won't make any sound because my laptop speaker remained inactive, and once i unplugged it my laptop went back to active and made sounds.

 

Please help, i've tried to reinstall the audio driver but it didn't work.

 

whenever i restart my laptop or wake it up from sleep it will work again, but only once on first plug. but on second trial of plugging it back, it won't work again. 


is this hardware issue ? or software issue ?

Re: Yoga 720 13 audio jack detects headphone on first plug only

I have this exact same issue on my T560 thinkpad.

 

It is the same whether I'm docked or not. I have speakers plugged into my dock and listen to music through them all day long. But as soon as I undock and then redock, the speakers won't play and the T560 doesn't recognize the dock audio jack, or the actual laptop audio jack, until I restart the laptop. Not just sleep or hibernate, but hard restart. It is very consistent at least. I have reinstalled the drivers both from lenovo and realtek - no love.

 

HELP

I had my Yoga 720 sent for warranty and they fixed it. It seems like they replace my motherboard as i don't have a serial number anymore. 

As what i notice is that if you don't get audio jack notification on action center, i think there's a problem with your audio driver. I remembered that i messed it before it went like that. 

You may want to send it for warranty or repair.

I have this issue as well with a T460. The headphones are detected after the first plug in from a restart. Any time I replug them in after that, they won't be detected--sound will only continue to play via laptop speakers.

Nice work!
Can't imagine why Lenovo doesn't push this out or at least have it as an option on their support site.

Yeah I spoke too soon. It doesn't work and the link is dead now. 

 

Lenovo really needs to step up and put pressure on realtek to fix this **bleep**.

Hi,

Did lenovo accept your laptop for warranty repair with the said audio problem? They dismissed my complained as "it's a SW problem, we only cover HW".

NB the problems with my yoga 720 started on day 1, I reported to lenovo support after couple of weeks. Pretty crappy attitude, stating that two-weeks old lenovo laptop's issues is not their responsibility anymore.
