IC-7410 Audio Interface and ALSA (2)

For the playback, IC-7410 seems to accept the audio data at least with three different sample rates, namely 32kHz, 44.1kHz and 48kHz.

It does not work with these sample rates.

You can hear the sound with the Monitor function of IC-7410, if you set the “DATA OFF MOD (menu item no. 40)” to “USB”, and push the “TRANSMIT SWITCH” on, preferably using a dummy load.

% cp ./alsa-lib-1.0.28/test/pcm.c pcm2.c
% gcc pcm2.c -o pcm -lasound
(you need "asoundlib.h", which you can find in "alsa-lib-1.0.28/include".)
