Hi everyone,
I need your help. I can't get any sound from the device in the subject.
I'm actually on Gentoo 64bit, vanilla kernel 3.3.0-rc2 with usb-audio
support and radio-si470x with usb support built-in. I'm using alsa 1.0.25.
When i plug the device I get the following dmesg:

Bus 006 Device 003: ID 06e1:a155 ADS Technologies, Inc. FM Radio
Receiver/Instant FM Music (RDX-155-EF).
Then I can see the new device /dev/radio0 and in alsamixer there is the
new usb audio capture device.
The problem is that I can't get any audio from it. If I try to "cat
/dev/dsp1 > /dev/dsp" I can hear some noise, but I can't tell if that is
the normal noise of the fm signal or what else.
I also tried with the "radio" utility. It doesn't do anything whatever I
try. Also it gives me these errors (popping out from the red background)
VIDIOCGAUDIO: Inappropriate ioctl for device │
VIDIOCSAUDIO: Inappropriate ioctl for device
If I try to "radio -c /dev/radio0 -i" to scan for available freqs, it
just goes from 87.5 to 108.00 in a couple of seconds finding nothing.
I've tried also with a stock Ubuntu 11.10, with exactly the same
results. Also the first time I plugged the device the software version
was 0; then I tried it with Windows 7 (where it works), and it updated
the software to version 1.
So, I'd like to get this device to work; please tell me if there is any
informatio you need to figure out what's going on.
Thanks, Daniele
