rplay README.linux - notes for Linux users.
Linux support is based on the Open Sound System driver included with
most Linux kernels.
/dev/dsp is used by default with CD quality output -- 44100 Hz,
16-bit, 2 channels. These parameters can be changed using the
--audio-* command line options and/or ~/.rplaydrc.
When /dev/audio is used, rplayd uses 8000 Hz, 8-bit, 1 channel, and
ulaw output.
/dev/mixer is used to control the volume and configure output ports.
rplay supports headphone, lineout, and speaker. Ports that aren't
enabled have their volume set to zero.
The --audio-fragsize rplayd option can be used to control audio device
buffering. Fragment sizes must be a power of 2 greater than 16. By
default, rplayd lets the audio driver pick an appropriate fragment size
which has about a 0.5 second delay. Example sizes:
256, 512, 1024, 2048, 4096, 8192
DSP_BUFFSIZE in the kernel sound driver may need to setup with
a different value to improve audio performance. 65536 is known
to work well with rplay. If you hear gaps, clicks, pops, etc., try
increasing this value.
Reading audio from CDROM uses /dev/cdrom by default. Make this a
symbolic link to your real CDROM device. For example:
lrwxrwxrwx 1 root root 8 Oct 1 12:46 /dev/cdrom -> /dev/hdc
/dev/cdrom1, /dev/cdrom2, and /dev/cdrom3 can also be created if
available. Tracks can be played using:
$ rplay cdrom: # play entire CD
$ rplay cdrom:5 # play track 5
$ rplay cdrom:1-3 # play tracks 1, 2, 3
CDROM support only works on ATAPI CDROM devices, I think.
