Leif,
Thanks to your nice videos, I have installed Linrad very easily on my Raspi.
One issue remains however. I'm using an external USB sound card (EMU-0202) capable of 192 kHz SR (the same I have been using for years on my WinXP computer + Softrock).
In Linrad, in the "U" section (A/D and D/A setup for RX), I define that sound card as input (A). I set the sampling rate to 192 kHz. I want to listen on that same card. So, I select it as output (B) too (as I used to do on the WinXP computer).
Starting Linrad, I see the whole 192 kHz bandwidth. All works as expected except the output sound, it is full of "hissss" and distorded (something around the sampling rate I supposed).
So, I checked in Chromium (Inet browser in the Raspi) and I can play sounds (for example YouTube) without problems.
I tried to change the sampling rate of the input in Linrad (A) => 48 kHz instead of 192 kHz and then, all is OK, the sound is normal and as expected.
So, it seems the output sampling rate in the sound card is correlated with the input one.
Any idea on how I could solve that issue ? I'm not used to ALSA, etc things.
One workaround is to send streams over my home LAN towards another computer. It works but I would prefer to have all on the same Raspi.
Thanks in advance.
