Vostro 1000 Audio In Problems
Hi,
Ive just purchased a Vostro 1000. Ive tried plugin an audio device in through the line in socket but theres no sound through the PC speakers. Ive checked all the sound options in Vista Home Basic, but all you have in Speakers/Headphones - Levels - is a speakers icon. Ive seen other laptops that have line in muted, but i cant even find a line in level.
Sound driver is - SIGMATEL STAC 92XX C-Major HD Audio
Would be grateful for your help
ps ive already tried downloading the latest driver on the dell site but that hasnt worked

=================================================
=================================================
Dell ships with the ability to monitor the input jack turned off. For models with the Sigmatel 92xx audio chip & driver an edit in the Registry of the value EnableInputMonitor will restore the monitoring function. However this value is not included in the Registry of Windows Vista operating system and so you must type it in.
[Create a System Restore point before editing the Registry! To create a new Restore Point go to Start/Help & Support/System Restore and tick 'Create a restore point'.]
1. Go to the Start menu and click on Run.
2. Type 'regedit' without quotes and click OK to open the Registry.
3. Click on File/export and save a copy of the Registry to your desktop (optional if you created a Restore Point).
4. Using the + signs in the left pane, navigate through the registry to get to this location:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0000\Settings\filter\SpeakerHp
5. Click on the key SpeakerHP to select it.
6. In the right pane, right click and select New > Binary Value.
7. Type 'EnableInputMonitor' without quotes and then press Enter.
8. Right click on the new name and select 'Modify'.
9. In the 'Value data' box, add 01 to the existing 0000, then click OK.
10. Exit the Registry and restart the computer.
11. After restart, enable input monitor in audio properties.
(Right click your speaker in program tray. Click Playback devices. Right click on Speakers/Headphones and click properties. Click on levels tab. You will now see a box saying input monitor. Click the speaker picture.)
(Thanks to forum members ethan_hines, fuzzy34, and chef moore for figuring this out.)

If muting the Input Monitor control on the playback tab doesn't mute it I don't know what else to try.

got close to thinking it was fixed, got all the way to the 0000 folder in registry it has no + folder to open for Settings\filter\SpeakerHp....? I did a system restore because I had previously updated the driver thinking it had changed it's registry
Anyone have the same issue?

Two points
Models with Windows XP and a Sigmatel STAC 92xxHD Audio Chip
The following set of instructions is only for these and similar models with the Sigmatel 92xxHD audio chip running Windows XP :
B120, B130/1300, 6400/E1505, 9400/E1705, E1405/640m, XPS M140/630m, 1420, 1520, 1720
Latitude D420, D520, D620, D820, etc, and any others with the Sigmatel 92xx HD chip and Windows XP.
On these models running XP, monitoring can be restored by editing the Registry subkey EnableInputMonitor.
[It is wise to create a System Restore point before editing the Registry! To create a new Restore Point go to Start/Help & Support/System Restore and tick 'Create a restore point'. Even better is to save a backup copy of the Registry by using its 'Export' utility.]
1. Go to the Start menu and click on Run. Type 'regedit' without quotes and click OK to open the Registry.
2. At the top of the list, highlight My Computer.
3. Under the Edit menu, select Find.
4. Type in 'EnableInputMonitor' without quotes and click 'find next'.
5. Highlight EnableInputMonitor. Right click on it and select Modify.
6. Highlight 00 and change to 01. Click OK.
7. Repeat "find next" (F3) several more times and keep changing values to 01 until the "EnableInputMonitor"'s coming up are of the proper value.
8. Find a key named "EnableIntSpkrMute" and change its value from 01 to 00.
9. Exit the Registry and restart the computer.
Next, configure the system mixer:
1. Open Volume Control by right clicking on the speaker icon on the taskbar, or go to Start/Control Panel/ Sound & Audio Devices Properties/Advanced (button).
2. Under the Options menu, select Properties.
3.Under 'show the following volume controls' check the box next to Input Monitor. Click OK.
4. Make sure the mute box is unchecked. Unfortunately the slider itself will be frozen in place and won't control the outputted volume.
(Thanks to forum members emann15 and The Performing Flea for figuring this out. I have put it into this step-by-step format for those of us who are not familiar with editing the Registry). This is the direct Registry path to the key:
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\
{4D36E96C-E325-11CE-BFC1-08002BE10318}\0005\Settings\filter\Rear

Sorry but I don't know. The instructions work with most models but you never know, particularly with Vista.

The original poster in thgis thread got the instructions to work on a v1000 with Vista in August '07. The Vista audio driver current at that time was
Sigmatel R153910, v 6.10.0.5407, released 7/11/2007.
Assuming you have Vista and the newest driver, try installing that older driver and see if it helps.

If it's XP then notice what I said earlier about the driver. The instructions will not work with the Sigmatel audio driver R171789 (v.5.10.0.5515) that was released in December '07. That is the driver that has stereo mix. To enable monitoring you must have an older driver installed (but I don't know of an older XP version for the v1000, try R122161), but in that case you not have stereo mix.

Well i went with realtek instead of this BS sigma junk since it's much easier and is probably just as good.
It's working well atm no harm done but it's still to early.
BTW thanks for taking the time and trying to help me means alot since i know nothing of this stuff. It's really just weird trying to do all this stuff....well for me it is.
