No. To generate the analog signal to modulate an FM transmitter
for stereo you need at least 53 kHz usable bandwidth with a flat
amplitude respnse and perfect linear phase. The minimal practical
sample rate would be around 120 kHz. No audio interface I know of,
not even those work at 192 kHz, can do this.
You'd need an 'instrumentation/laboratory/scientific DA converter
for this to work at all.

There are three of them, and Alleline.

I'm using the Alsa driver as set up by Ubuntu. Would the OSS driver
be a better choice? - I have an AD1986A codec chip on my
motherboard.
- According to its datasheet, AD1986A supports 96 kHz sample rate.
- /proc/asound/card0/codec#0 doesn't list 96 kHz.
Why?
Because:
* A particular HW design does not have to support everything
a chip could do.
* A driver does not necessarily support all hardware features.
