If I tune using old radio it works. If I tune using latest radio but

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?
