FreeBSD 5.3-BETA6 loads the snd_maestro driver however you get no playback on the machine. 

pciconf says:
none4 at pci0:12:0:        class=0x040100 card=0x00011179 chip=0x1978125d rev=0x10 hdr=0x00
    vendor   = 'ESS Technology'
    device   = 'ES1978 Maestro-2E Audiodrive, ES1970 Canyon3D'
    class    = multimedia
    subclass = audio

then cat /dev/sndstat:
pcm0: <ESS Technology Maestro-2E> at I/O port 0xee00 irq 11 kld snd_maestro (4p/0r/0v channels duplex default)

Just for the record this is a Toshiba Portege7020CT.

Recording interface seems to load, just no playback.

I have searched the forums and noticed it worked last in 5.1.
I have installed both 5.2.1, then 5.3-Beta6 because I noticed in the 5.3-Beta release notes it says fixes for the Maestro card are included. However, after testing they don't work with any release newer than 5.1.
Seems to either go to 4.x or 5.1.
