How do I use Ogg Vorbis file with WAVEFORMATEXTENSIBLE?

I'm using libvorbisfile to open an ogg vorbis file and playing it using DirectSound but faced with the difficulty of filling in the information needed to be passed to the DSBUFFERDESC data structure.

I managed to use ov_info() to obtain the sampling rate (48,000Hz for quality 10 ogg) and the number of channels (usually 2 in my case). But there isn't any attribute of bits per sample (8 or 16).

Please guide me on this one, thanks. Currently, I am only capable of filling my own settings to WAVEFORMATEX data structure instead playing at 16 bits, 44,100Hz, 2 channels. This is clearly different from the ogg vorbis sample file I'm using which is of 48,000Hz. Therefore I must use WAVEFORMATEXTENSIBLE.
