No sound in right speaker from UD-3000 speaker audio port.


#1

LAPTOP = HP Envy 15
OS = Windows 8.1 Pro 64-bit
PLUGABLE DRIVER = 7.7.58332.0 (driver date 2014/10/22, by DisplayLink Corp.)
EARPHONE = Samsung Earphone included with Galaxy Nexus (Nexus 3)
SPEAKER = Built-in Speaker of IODATA LCD-MF231X Monitor.
PRODUCT = UD-3000, Rev B2

I have a UD-3000 as my docking station. Plugable Audio is set as the default device with either earphone/speakers attached. I can hear audio, but only from the left speakers. There is no audio coming from the right.

Now when both speaker/earphone are attached to the built-in audio port of the laptop, both works fine. How do I resolve this issue? Please help. Thanks!

Hi Marc,

Thanks for posting. I’m sorry the audio isn’t working properly from the dock to your monitor’s speakers. I’d be happy to help.

You have done a thorough test to validate your speakers, cable, etc. are working properly from a hardware perspective. Let’s focus on software. Windows does allow you to change the levels of the individual channels of a playback device. If you would let’s check those to see if the right channel is muted for the Plugable Audio device.

Please right-click on the speaker icon located in the lower left-hand corner of the desktop and select ‘Playback Devices’ from the menu. Double-click on the Plugable Audio Speakers. Click on the ‘Levels’ tab. Click on the ‘Balance’ button. Is the right channel muted? If so drag the slider to match the output of the left channel (screenshots attached).

If that doesn’t fix the issue please send an email to support@plugable.com and we can go from there.

Thank you,

Bob

I have checked it and found that both left and right are not muted. In fact they are at 100%. See the picture below.

I have tried performing a “speaker test” also:

This is the result using UD-3000 Plugable Audio:

This is the expected result (used the built-in Realtek audio device):

Do you think I got a defective product? :frowning:

Hi Marc,

Thanks for checking and reporting back. I haven’t seen an instance where a dock’s audio failed in this manner yet, but all things are possible. Please send an email to support@plugable.com with ‘Ticket 85378’ in the subject line. Please include your Amazon Order ID number and preferred shipping address and we can get a pre-tested replacement sent out to you. That will help confirm if the problem is in the hardware itself.

Thank you,

Bob

Hi Bob,

Good morning.

To be honest, I asked someone else to buy this in the U.S. before shipping it here in the Philippines. As such, I don’t have an Amazon Order ID, and I am not sure if your company would allow shipping to the Philippines… :frowning:

What are my option here? :smiley:

Regards,

Marc

Hi Marc,

Thanks for getting back to us. Unfortunately we cannot ship to the Philippines. My recommendation would be for you to have the person who purchased the unit contact us using the same information I posted earlier and we can get the replacement to them. Once they have it they could forward it on to you.

Thank you,

Good morning.

Thanks for the prompt response. I will try as you have said. Will get back to you. Thanks!

Hi Bob,

Good afternoon.

Would I be required to return my current unit? Thanks!

Regards,

Marc

Hi Marc,

Yes you would be required to return the original unit. Once we receive the original we will want to test it to determine the source of the failure.

Thank you,

Hello Bob,

Good morning!

I have decided to keep the current product with me. I will just put up with this minor limitation. Sending the product back to the US is both impractical and uneconomical in my part. So let’s close this item as an isolated case (probably some hardware failure in my UD-3000, talk about bad luck).

Thank you so much for the time and assistance. I really appreciate it.

Regards,

Marc
