Hi mhahn
Searching about it on internet led me to one of the RasberryPi's forum Raspberry Pi • View topic - USB soundcard...Finally good (non HDMI) Analog Audio ,wherein it says that "Alsa can sometimes be a pain, the recording rate 8000Hz you chose for arecord is probably not supported by the card."
Do you know how can I get sampling rate of 8000Hz to work with alsa ? Or do you suggest an alternative to alsa for Galileo?
