PCSEL(1)

NAME
pcsel - PC-Speaker and DAC device driver configuration utility

SYNOPSIS
pcsel [ options ]

DESCRIPTION
pcsel enables the configuration of /dev/pcsp at system startup or for testing new devices. Without options pcsel reports the actual output-device and its parameter.
Note that Stereo-on-One is autodetected at kernel startup and enabled as default device (otherwise PC-Speaker is chosen). If you enable Stereo-on-One the right lp port is detected automatically, that is wrong port will be rejected (if selected).

OPTIONS

-d device
    set the output-device:
        'Sto1' : Stereo-on-One
        'DACm' : Mono DAC
        'DACs' : Stereo DAC
        'PCSP' : PC-Speaker

-p port
    the lp port to use (0-2) for single DAC

-r rp -l lp
    the lp ports for two DACs

-s Hz
    set the virtual sampling rate to Hz; this is only necessary for /dev/pcsp access by cat or dd

-S  set Stereo if possible

-M  set Mono

-e on|off
    enables or diables the 16bit stereo emulation

-b real sampling rate
    set the real sampling rate for playing thru PC-Speaker, this MUST be less than the maximal sampling rate which is measured by the driver;
    'pcsel -b max' set the maximum possible sampling rate

-v volume
    set the volume for PC-Speaker in %

-h  usage information

BUGS
Because /dev/pcsp can only be opened exclusively, you cannot configure the driver while another program already opened the device.
