Having problems with your HP NB199UA Pavilion Notebook ?

HDMI cable from laptop to TV; picture on TV sound on laptop.

\015 I bought an HDMI cable, which I plugged into my TV. For about a week it worked perfectly; I would select HDMI1 on the TV and then toggle it back and forth between TV only, TV & Laptop, and Laptop only by hitting Function F4. The problem is that now when I do it, I can't get the sound to come out of the TV--it's only coming out of my laptop, which has terrible speakers. I don't know what caused it; it worked perfectly until just this morning. Any help?!\015\012\015\012NOTE: I'm using iTunes, and I just noticed that when I change the volume on my laptop, iTunes stays at the same volume; it seems that now in order to change the volume, I have to use the volume bar in iTunes itself. Is this a hardware issue, or a software?\015\012\015\012SECONDARY NOTE: It is actually an HP Pavilion dv4-1225dx Entertainment Notebook PC, but there wasn't an option for this under "What product is it about?", so I chose the closest thing they had.\015

Hi there,
\015\012
\015\012Sounds like you may have just had either a settings change when installing or adjusting one of your other media programs that has stopped it from working the way it should or, may have just got some automatic updates either from HP or Microsoft that forced a similar change.
\015\012
\015\012The reason the sound isn't going through the HDMI is likely that the laptops soundcard is stuck on the speakers setting and needs to be switched back to digital.
\015\012
\015\012For the moment, try opening your start menu, then control panel. If it's not in classic mode you can switch it by clicking the classic mode link in the top left of the window. Scroll down to the sound icon and double click it. You should have 2 or more icons in the middle. If the one that's called "Speakers" has a green check mark that means its set to use the laptops built in speakers. If this is the case to switch to the digital output on the HDMI simply put your mouse on the digital icon, right click it and set it to default.
\015\012
\015\012If this only corrects the problem to the point where it now work on the tv but won't switch back then you likely had a windows update change something, if this doesn't work at all or if you no longer see the Digital icon then it likely means something in your Video driver may have been damaged(or just changed) due to an update. This is because the adiou out in the HDMI is actually coming from your video card.
\015\012
\015\012Either way you can try two things to fix it. First go into start menu, All Programs, Recovery Manager if it's a single Icon just click it if there are 3+ look for the one about applications and drivers and click that. The recovery manager will ask what you want to do more than once say no or next until the "Application & driver" option presents itself then take that option. This will allow you to change both your sound and video drivers back to factory.
\015\012
\015\012It will ask you Applications OR Drivers, select drivers then follow the prompts to find your sound card driver. Re-install the factory driver and then restart the laptop. If it Works you're done. If not repeat the previous sections but re-install the video card driver and restart then test again.
\015\012
\015\012If that doesn't work drop me a comment here and I can give you a few more pointers
