28 * - USB Audio is provided by the alsa snd_usb_audio module.
29 * For listing you have to redirect the sound, for example using:
30 * arecord -D hw:1,0 -r96000 -c2 -f S16_LE | artsdsp aplay -B -
31 * - regarding module parameters in /sys/module/radio_si470x/parameters:
32 * the contents of read-only files (0444) are not updated, even if
33 * space, band and de are changed using private video controls
34 * - increase tune_timeout, if you often get -EIO errors
35 * - hw_freq_seek returns -EAGAIN, when timed out or band limit is reached
