[Linrad] Re: Linrad-02.45 ALSA/4Front

Hi Leif,

At runtime level , the function " display_sdi "  in lsetad.c already
checks whether OSS or ALSA is installed.
This is done in a similar way as described by Roger W3SZ, by checking
the presence of the file /dev/sndstat  for OSS or the
file /proc/asound/oss/sndstat for ALSA.
