DSOUND: noise with aRts driver

["Jerry Jenkins" <Jerry_J_Jenkins@hotmail.com>]

Changes:
1    dlls/dsound/dsound_main.c :
    Added waveOutSeVolume when open sound driver for dsound. Otherwise, there is no sound if we use aRts.

2    dlls/winmm/winearts/audio.c :
    Modified volume_effect8 for taking unsigned data as singed data, and wodPlayer_WriteMaxFrags because of wrong data length which lead to strange noise and volume control working incorrectly.
