M-audio audiophile 2496 & FreeBSD

I have a sound card "M-audio Audiophile 2496" and I have no idea how to run the sound. I tried loading different drivers from /boot/loader.conf but no result.

It's not a typical sound card and I don't see any threads for that kind of card. If you can help me I will appreciate it.

Regards
 
Try loading snd_driver and see if that detects anything. If it's not detected it's not supported by the default FreeBSD drivers and you may need to resort to audio/oss.
 
After installing kde4 the OSS got the sound but the sound is 16 bit, any idea what i have to do to get it to 24 bit?
 
I found that the right driver for M-audio audiophile 2496 is "Envy24". I didn't have the time to listen to something before. There is a slight disbalance between left and right. I don't see a lot of controls for the device, do you know how to control the balance to even the left and right?
 
I get
Code: 
ugen0.5: <Audiophile USB tm M-Audio> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (0mA)

and

I can't change dev.pcm.6.play.vchanrate, it stays at 96000, no matter what dev.pcm.6.play.vchanmode.When I try to play, I get some pulsating noise.
 
This is now 7 years old and still not working (in 12-STABLE):
/dev/dsp2.1 and /dev/dsp2.2 are created but don't appear in audacity to play or rec.

On the FastTrack Pro I actually can play sth. back (with mpv, tested with headphone) while with the Audiophile I only get white noise.
I can't select the recording device.
... Actually recording works when I select /dev/dsp (FastTrack) ...

Just take a look at snd_envy24(4) and you’ll see that the driver only supports stereo output, no recording. I had one myself many years ago. Good audio quality, but the driver won’t let you use it’s full potential.
