_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of AndyNgo Sent: 2007年1月19日 17:03 To: [email protected] Subject: ***SPAM*** Score/Req: 09.90/05.00 - Fwd: Does the oss sound driver support mono? I can't seem to set the OSS sound driver to mono mode (via SNDCTL_DSP_STEREO ioctl call). It's always set to stereo mode. Does that mean I need write a function stereoToMono to convert the raw PCM data to mono and vice versa a function monoToStereo to play it back out? I need the data to be in mono mode to use a codec. Regards, Andy
