if winejack.drv can nly supply only jack server'sample rate

wwo->sample_rate = fp_jack_get_sample_rate(client);

but in waveoutcaps , it incorrectly state that it can support 16bits 11025Hz,
22050Hz and 44100Hz if the jack server is running at 48000Hz


 948 /* NOTE: we don't support any 8 bit modes so note that */
 949 /*      WOutDev[i].caps.dwFormats |= WAVE_FORMAT_4M08;
 950       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_4S08; */
 951       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_4S16;
 952       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_4M16;
 953 /*      WOutDev[i].caps.dwFormats |= WAVE_FORMAT_2M08;
 954       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_2S08; */
 955       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_2M16;
 956       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_2S16;
 957 /*      WOutDev[i].caps.dwFormats |= WAVE_FORMAT_1M08;
 958       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_1S08;*/
 959       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_1M16;
 960       WOutDev[i].caps.dwFormats |= WAVE_FORMAT_1S16;
 961     }

It only 16bit and WAVE_FORMAT_48M16 | WAVE_FORMAT_48S16 by providing 16bit ->
float conversion

if you start jack server at 96000Hz, winejack.drv should WAVE_FORMAT_96S16 |
WAVE_FORMAT_96M16 in waveoutcaps

to get best result , you should start the jack server at 44100Hz
