I have been trying to put some music to my Taranis SD card for background playing without success. I watched the Scott Page's YouTube video how to do that and read the comments about the PCM changes on newer OpenTX FirmWare (I'm using the newest at the moment 27xx something. Can't remember). I'm familiar with Audacity for couple years already and have been doing different kind of audio edition with computer atleast 15 years already, so it isn't new to me.
Okay, what I have been trying:
- First created a new model then set a custom function to switch SB- to set VOLUME from S1 and activated it. That is working.
- Then I set second CF to same switch SB- to play BGMUSIC and chose a file from SD-card (default battery low alarm). That is working, playing it repeatedly.
- Then I have multiple different kind of tries to make new sounds, but no joy.
1. Opened MP3 to Audacity. It was 44100 stereo with 32 float sample format. I converted it to Mono (as Scotts video) and exported as WAv (Microsoft) Signed 16 bit PCM. No joy
2. Opened same MP3 again to Audacity, converted it to mono and resampled to 32KHz. Exported same as on 1st phase. No joy.
3. Then I converted to mono, changed sample to 16 bit PCM, exported as other uncompressed format and 16 bit PCM. No joy.
4. Again converted mono, changed 16 bit PCM, re-sampled to 32KHz, exported couple different formats (U-law, 16 bit PCM and maybe some other. Cant' remember all anymore). No joy.
5. There was multiple tries with different kind of settings and all was no joy.
Then I got frustrated and opened one of the existing sound files from SD-card to Audacity. Checked that it's mono 32KHz and 32 bit float. Exported that (with different name) to SD-card as WAV (MS) Signed 16bit PCM and it was working flawlessly. Tried once again to do that for MP3 file with exact same settings as that existing wav, but no go.
What the heck I'm missing here!?
