Unknown device/hdmi to TV issue

HP dv7 1127cl
Microsoft Windows 7 (32-bit)

I recently upgraded my old Pavillion dv7 1127cl to windows 7 ultimate 32 bit. Hooked up hdmi to RCA HD TV. Video is great but of course no audio. Under sound it list as Realtek HDMI Output, but ATI HDMI Audio and not plugged in is grayed out and cannot be set to default. I have tried downloading hdmi drivers but didnt do anything. BTW, laptop has sound, np there.  In device manager I have one conflict. Under other devices I have unknown device. Hardware Ids ACPI\HPQ0004. I saw there were  fixes in your forums for the latter issue, but was unsure if the download recomended was compatable with my laptop. Anyway, Im mostly deaf from the military and my laptop just doesn't have enough volume.  Thanks in advance for the help.

Hi,

 

What is your HDMI to RCA adapter ? Note: HDMI use digital signals and RCA uses analog signals. You NEED a proper converter.

 

Regards.

Unknown device/hdmi to TV issue

Hi:

 

This is the driver you need for the 0004 device...

 

This package provides HP 3D DriveGuard for the supported notebook models and operating systems. HP 3D DriveGuard receives notifications from the integrated accelerometer and protects the hard drive (HDD) by automatically "parking the heads" to reduce the risk of damage if the notebook is accidentally dropped or is abruptly impacted by another object.

OK the drivers you sent corrected the unknown device issue Thank you for that. However, I still have no sound to television. I guess the two issues weren't related. In reguards to the previous post, I have an RCA (brand name) TV. I have connected the HDMI cable from the laptop directly to the HDMI input behind the TV. No adapter was used. As I stated the video is perfect I just can't get sound to the tele. Thx again.

You're very welcome.

 

Unfortunately, I wouldn't know what you can do about the audio out of the HDMI port not working if you already tried the ATI HDMI audio driver from the realtek website.
