Alsa does not support my (SB X-Fi Xtreme Audio CA0110) audio card as shown in their web page.
Now my question is how can I configure my audio driver without using ALSA? And should I waste my time trying to make this audio card work or it is simply impossible for linux?
Development on ALSA's ctxfi driver generally is very plodding due to lack of open data sheets (so putting pressure on Creative to provide them without the mandatory NDA may help here). You may have better luck with a very recent ALSA snapshot at https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules or OSSv4.2 at http://www.4front-tech.com/developer/sources/testing/gpl/oss-v4.2-buildrc3-src-gpl.txt. Be aware that choosing the latter route requires significant time investment (but is possible).
