Re: Yoga 2 pro sound problem

2015-01-29, 17:09 PM

I've had all the problems mentioned in the thread and then some. I tried all proposed solutions (pluggin/unplugging the jack, muting/unmuting, installing latest realtek drivers, playing with settings, etc.) to no avail.

 

Earlier today, I had sound on one channel of the earphones, with still white noise, and no sound on the speakers when the earphones jack was unplugged.

 

I uninstalled Realtek drivers (through Windows install/uninstall software), which solved the white noise issue, but not the speakers issue.

Then, while the jack was in, and some sound playing, I closed the laptop's lid, putting the computer in sleep mode, removed the jack and reopened the lid. Internal speaker sound came back.

 

This clearly points out to some software issue, not dealing correctly with a combination of events: jack put in/out while the computer is in sleep mode. I've had the issue before with the same type of combination of events, where the earphones would not produce any sound, and it was usually solved by muting/unmuting while the earphones jack was plugged.

 

Now, to fix the wireless adapter instabilty issues... I still love my Y2Pro, despite all its small glitches.

 

I hope this helps.

I replicated this solution with my Yoga 2.  I inserted the headphones, closed the laptop lid, waited for the sound to stop due to laptop sleep, unplugged the headphones, opened the lid and my speakers worked again.  Definitely a software issue.

A few days later... for me, this works most times, but not every time. 

Even more bizarre: my speakers suddenly stopped after a couple of hours without problem.

Note that I uninstalled the Realtek driver, so either there are still traces of it (unlinkely) or it's a deeper issue. Firmware on the sound board?

The investigation into these reports has concluded.

 

I appreciate everyone taking the time to provide feedback and work with me as I investigated. My sincerest thanks to Maricat for allowing me to borrow her Yoga 2 Pro as a customer sample.

 

If you have updated your audio drivers and checked your settings yet the headphones or speakers on your Yoga 2 Pro is intermittantly not producing audio, please contact Lenovo Service for support and reference Service TIP SF15-I0002/ HT102554.

 

Thank you,

I cannot find the Service Tip on the Lenovo Service website. Would it be possible to post a link to the location?

Call Lenovo support and ask them to look up the service tip. It is not publicly available.
I don't work for Lenovo. I'm a crazy volunteer!

Thank you for that. I called Lenovo in Thailand and they have no idea what I am talking about. This tip must be extremely embarrassing to warrant such secrecy.

If somebody who has access to Lenovo Support in the US and can tell me what the alleged Service Tip is about, it would be much appreciated.

Thanks

I have now contacted Lenovo Support by phone in Thailand and some other place (India?) and they claim to have no knowledge of Amy's alleged Service Tip. Can anybody in the US tell me what it is please?

How about just telling use what that service tip is? This process seems rather beaurocratic. Can't you post a link to the service tip?
