This sound-card is not yet recognized by HAIKU.
The card is working fine in ZETA.
It is a C-Media CMI8338/8738 based card and should work…
It uses YMF744-B-V remarked chip.
…there is a driver in the repository, but it may not be included in the nightly images by default. You may want to ask on the development mailing list; you can subscribe from here:
The driver is using the old audio API thus, unless the “LegacyAudio” media add-on is fully implemented (and working), you won’t get any sound despite this driver works ok (for playback, at least, in R5).
This situation also applies to other drivers, like the sis7018, and most sound drivers from BeOS R5.
