Hi! Sorry for my bad English...

Please help me to solve problem with sound in notebook Toshiba Satellite C850-B1K <part number PSKCAR-00X00GRU> (with latest pre-installed BIOS) and FreeBSD 9.1-RC1-i386.

Works only beeper in console (if mixer igain > 0), when I am press Backspace key at beginning of line, and works beep in XFCE 4.10 Exit menu. Music files are not played (zero time counter in xmms, when press File Play button ). May be incorrect sound system configured.

I am try to use sysctl hw.snd.default_unit=1 but it did not help.

On Win 7 & Linux Mint 13 sound play fine out the box. Please, help me! PR N 171937
