If I tune using latest radio but with option -l 0 (./console/radio -l 0) it also works. Using "arecord -D hw:2,0 -r96000 -c2 -f S16_LE | aplay -" to listen. So it seems that latest radio with alsa loopback is only having those problems.Ok.These are the patches: radio-si470x: Don't unnecesarily read registers on G_TUNER radio-si470x: Lower hardware freq seek signal treshold radio-si470x: Always use interrupt to wait for tune/seek completion radio-si470x: Lower firmware version requirements And from that I can see it loads new driver as it does not warn about software version - only firmware.Right, so what I want to do is to lower the firmware requirement to 12, so that it won't complain for your device since that seems to be working fine. Does that sound like a good idea to you?
Yes, indeed lower it to the 12 as it works to get rid of those warnings. It still cracks but rarely, once per 2 mins or so when using arecord + aplay.
The whole journey of playing that device was idea to learn V4L2 radio API as I was planning to add SDR functionality. Anyhow, I am a little bit disappointed because that radio uses snd-usb-audio module for audio. Do you know any cheap usb radio which uses vendor specific USB interface, not standard profiles?
