Vista - Realtek, 6.0.1.5322 functional issue.

Hello all, my first post here, nicely formatted site. My System is in my sig.
My 1y old Toshiba laptop w/Vista, using Realtek sound driver version, 6.0.1.5322.
I had the left speaker go out. I ran through all system diagnostics. I checked for updates and found I have the latest driver. I then pulled the keyboard and disconnected both speaker leads from the board. Connecting the left speaker lead to the right board plug in, the speaker dose work. I then connected the right speaker lead to the left board plug in, and got no sound.
FYI when I plug in the head phones only the right side works as well.
My question is, based on information currently out there, is it likely I have an issue with the board or is there a known issue with the driver that would cause sound to go out on one side?
Thanks ES

Hi eurosid and welcome to Vista Forums

Have you checked the setting of the balance control? What is the model number of your laptop?

Hi Dwarf and thanks for the greeting. I thought my system details saved. Here they are.

-07 Toshiba satellite A135
-vista home premium, 32 bit
-pentium dual-core 2g RAM
-Intel, 2g processer
-160g hard drive 41% in use
-SP1 updated, NOV 08

Under speaker properties, level tab, I went through all of those options also testing the headphones, which all were balanced. I tried changing the balance to see if something in the configuration changed but that did not make a difference. That is why I pulled the keyboard and did the jumper. Always do the easy stuff first. I wondered if you could lose one channel within the sound driver.

Under sound I right clicked on the speaker icon then choose configure. Under that you can test L and R speakers under test it will play the left then the right speaker playing a tone. The view shows a graph to the right that when the speaker is clicked on plays a tone along with a visual sound display. The visual display is still functions when clicking on it but, no sound on the left side.

I ran a diagnostic on the system for any corrupt files of system changes with no results. Also, choosing update driver in speaker properties, allowing the system to search, it determined I had the latest driver.

Any suggestions?

Hi eurosid,

I assume that you have had full sound prior to this happening. What I suspect is that you might either have a faulty headphone socket or that the lead from that to the relevant point on your motherboard is damaged. Unplug this lead from the board and, using a can of compressed air (or a straw), blow into the connector to ensure that it is clean and free from dust which can cause a bad connection. Repeat with each connector and also with the headphone socket.

Yes I had full sound left and right. In my first post pulling the keyboard and checking connections was second to the first order of operations in my second post.

That is why I was wondering if it were possible to loose one channel in the pair within the driver.

Judging from all the information it does seem like you have a faulty hardware problem, If cleaning the left output did not work it seems that it may be bad. If you really want to be sure it has nothing software related your best bet is formatting the system.

I've got this, it works fine under XP, but only right channel under vista. Very odd???

I wanted to answer this again since I have not resolved this issue.

The both speakers worked at one time since this laptop is just over a year old. It was in November 08 the left one stopped working.

I unplugged the left speaker from the motherboard then ran a jumper to the right speaker motherboard plug in. The left speaker worked. I then ran the jumper from the right speaker lead to the left speaker motherboard plugin, it did not work.

I did not reinstall the driver but did update to the latest RT driver. I have not gotten any responces back from Real Tech support about this but I suspect they will refer me back to Toshiba.
