Yippe...i had the same set of problems and i think i got a solution to the problem...
i have a compaq presario F700 series laptop with Win XP(don't like Vista)...
all you gotta do is this...first setup a restore point.....then
go to the device manager in control panel...and disable the conexant hd audio device - venice 5045....

then update the device with another conexant hd audio smart audio 221. Do this from Control panel- system- harware - device manager- right click on the sound and game control devices on the disabled device and say install - have disk -select the location - , windows will give you warnings about how uncompatable this driver is.....ignore them.....apply,,,ok,.,,,,mic will start working and also sound will come only through headphones when connected and thru laptop speakers when its not....

SOURCE: low sound in headphone

I would say it is because the unit does not have a built in amplifier. The speakers are powered PC speakers of studio monitors I am guessing. Try plugging the headphones into the headphone jack of the speakers if they have a headphone jack or try a set of powered headphones out of the Edirol and see if it helps.

That should remedy the problem.

Error during audio driver installation

Hi Friends,

Try this out..

For Audio and Modem, download the following driver packs (install will fail, read below):
Conexant HDA Soft Modem with SmartCP
DriverVer=02/14/2007, (11MB)
Conexant High Definition Audio Device
DriverVer = 02/14/2007, (4.1MB)
After running the two Conexant packages above, the driver files will be extracted to C:\SWSetup\SPxxxxx. The automatic install program will fail but that is expected. Go to Control Panel > Device Manager. Single right-click on the ‘unknown’ audio device and select “Update Driver”. From the Hardware Update wizard:
Select ‘no, not this time’ when asked to connect to the internet, click next.
Select ‘install from a specific location’ (advanced), click next.
Select ‘Don’t search, I will choose the driver to install’, click next.
In the list of common hardware types, scroll down and select Sound, Video, and Game controllers, click next.
In the resulting dialogue box, click Have Disk.
Browse to the folder where SP36090 was extracted (e.g. C:\SWSetup\SP36090) and select CpV30D5a.inf, click OK
In the next dialogue, select Conexant High Definition Audio-Venice 5045. If you receive a warning that Windows cannot verify compatibility with this drive, select ‘Proceed’ or ‘Ignore’ (or whatever option that allows you to continue installing the driver).
When the driver is finished installing, restart your PC. Do the same thing for the modem, except the extraction folder will be C:\SWSetup\SP36089 and the INF is SprtHD5m.inf.
Restart and you should be good.
If you still have an ‘unknown’ PCI device, it is your touchpad and Quick Launch buttons. If you install the software for Quick Launch Buttons, the ‘unknown’ PCI device will go away, as well.
HP Quick Launch Buttons
