Hi all, Now I have mode 2020 running on Debian 9.9 on a Pi,
I'm doing some Speaker to Mic tests with different Audio adapters using the test file ./freedv-gui/wav/all_2020.wav Playing ./freedv-gui/wav/all_2020.wav on my PC, an i3 8100 through a C-Media USB device then speaker to the mic input to a SoundBlaster Play 3! on the Pi. CPU usage on the Pi gets up to 80% (of one CPU) (there are five more). This in [Spectrum] mode. The GUI display on my Main PC (ssh -Y user@host) The decoded audio ============= only small bits. Mode 700D with the same setup, almost 100% copy of ve9qrp_700d_int1_fast_snr2dB.wav Lockups in 2020 mode. ================ Though the Sync indicator is ON, often there is no speaker audio. Also once I had a 100%CPU lockup. FreeBeacon ======== Has the API changed such that "freebeacon" (with mods to set the mode) will work? Trials on my PCs (Intel), I'll do that and report in another email. ====== Hardware, my Pi ========== RockPro64 with Debian 9.9 from mkfixit2001, fixed kernel 4.4.171 Some say, "It's NOT a Pi", well, it's only extra is a PCIe slot over the "real" Pi3. Has Pi GPIO, HDMI, USB ports etc..
