Output rate - jmgtierrez - 08-26-2019

Hi All, I would like to know why the Moode+Raspberry is delivering an output rate of 32bits/44.1KHz when the mp3 track is decoded to 24bits/44.1KHz?

Thanks in advance 

Best regards 
Juan Manuel

Du you an equalizer activated?


RE: Output rate - Tim Curtis - 08-26-2019

Your DAC probably only accepts 32 bit.

My DAC is a Cambridge Audio Dacmagic Plus, it accepts 24 bits

Thanks

Download and run the alsa-capabilities command. It will print the encoding formats that ALSA thinks your DAC accepts.

Code:
wget http://moodeaudio.org/test/alsa-capabilities
sudo chmod +x alsa-capabilities
./alsa-capabilities

Example:
Code:
pi@rp2:~ $ alsa-capabilities
1) Analog output interface hw:0,0 (or hw:BossDAC,0)
- card name         = BossDAC                                                    
- card label        = BossDAC                                                    
- interface name    = Boss DAC HiFi                                              
- usb audio class   = (n/a)                                                      
- character device  = /dev/snd/pcmC0D0p                                          
- encoding formats  = S16_LE, S24_LE, S32_LE                                      
- monitor file      = /proc/asound/card0/pcm0p/sub0/hw_params                    
- stream file       = (n/a)

 Hi Tim, when I try access to http://moodeaudio.org/test/alsa-capabilities, I get a problem of permission

pi@moode3C:/ $ wget http://moodeaudio.org/test/alsa-capabilities

RE: Output rate - swizzle - 10-03-2019

Did you make any alterations to the software? You shouldn’t get a permission error on the wget so if that’s an issue I would suggest burning a new image. Moode is open source and users are welcome to modify as needed but it’s nearly impossible for Tim to troubleshoot problems if he can’t replicate the user environment.


RE: Output rate - adrii - 10-04-2019

Hi Juan Manuel

It looks like you are running wget in the root directory, '/', where you don't have write permission. Try changing to your home directory (run 'cd') and then run the commands there.

Adrian.
