I also respect him. - - -DISCLIMER -========= - - This driver is currently at early ALPHA stage. It may cause serious - damage to your computer when used. - PLEASE USE IT AT YOUR OWN RISK. - - -ABOUT THIS DRIVER -================= - - This code enables you to use your YMF724[A-F], YMF740[A-C], YMF744, YMF754 - cards. When enabled, your card acts as "SoundBlaster Pro" compatible card. - It can only play 22.05kHz / 8bit / Stereo samples, control external MIDI - port. - If you want to use your card as recent "16-bit" card, you should use - Alsa or OSS/Linux driver. Of course you can write native PCI driver for - your cards :) - - -USAGE -===== - - # modprobe ymfsb (options) - - -OPTIONS FOR MODULE -================== - - io : SB base address (0x220, 0x240, 0x260, 0x280) - synth_io : OPL3 base address (0x388, 0x398, 0x3a0, 0x3a8) - dma : DMA number (0,1,3) - master_volume: AC'97 PCM out Vol (0-100) - spdif_out : SPDIF-out flag (0:disable 1:enable) - - These options will change in future... - - -FREQUENCY -========= - - When playing sounds via this driver, you will hear its pitch is slightly - lower than original sounds. Since this driver recognizes your card acts - with 21.739kHz sample rates rather than 22.050kHz (I think it must be - hardware restriction). So many players become tone deafness. - To prevent this, you should express some options to your sound player - that specify correct sample frequency. For example, to play your MP3 file - correctly with mpg123, specify the frequency like following: - - % mpg123 -r 21739 foo.mp3 - - -SPDIF OUT -========= - - With installing modules with option 'spdif_out=1', you can enjoy your - sounds from SPDIF-out of your card (if it had). - Its Fs is fixed to 48kHz (It never means the sample frequency become - up to 48kHz. All sounds via SPDIF-out also 22kHz samples). So your - digital-in capable components has to be able to handle 48kHz Fs. - - -COPYING -======= - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2, or (at your option) - any later version. - - This program is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
