To find out whether the driver succeeded loading, -check the kernel log (dmesg). - - -ALaw/uLaw sample formats ------------------------- - -This driver does not support the ALaw/uLaw sample formats. -ALaw is the default mode when opening a sound device -using OSS/Free. The reason for the lack of support is -that the hardware does not support these formats, and adding -conversion routines to the kernel would lead to very ugly -code in the presence of the mmap interface to the driver. -And since xquake uses mmap, mmap is considered important :-) -and no sane application uses ALaw/uLaw these days anyway. -In short, playing a Sun .au file as follows: - -cat my_file.au > /dev/dsp - -does not work. Instead, you may use the play script from -Chris Bagwell's sox-12.14 package (available from the URL -below) to play many different audio file formats. -The script automatically determines the audio format -and does do audio conversions if necessary. -http://home.sprynet.com/sprynet/cbagwell/projects.html - - -Blocking vs. nonblocking IO ---------------------------- - -Unlike OSS/Free this driver honours the O_NONBLOCK file flag -not only during open, but also during read and write. -This is an effort to make the sound driver interface more -regular. Timidity has problems with this; a patch -is available from http://www.ife.ee.ethz.ch/~sailer/linux/pciaudio.html. -(Timidity patched will also run on OSS/Free). - - -MIDI UART ---------- - -The driver supports a simple MIDI UART interface, with -no ioctl's supported. - - -MIDI synthesizer ----------------- - -This soundcard does not have any hardware MIDI synthesizer; -MIDI synthesis has to be done in software. To allow this -the driver/soundcard supports two PCM (/dev/dsp) interfaces. - -There is a freely available software package that allows -MIDI file playback on this soundcard called Timidity. -See http://www.cgs.fi/~tt/timidity/. - - - -Thomas Sailer -t.sailer@alumni.ethz.ch |
