Distortion

[Tim Curtis]

Hi,

The lines below indicate the audio device driver (sndrpidac) either does not support hardware volume or doesn't detect the presence of a hardware volume controller on the audio device.

20200127 075625 worker: ALSA volume (None)
20200127 075628 worker: Hdwr volume controller not detected

There are a couple of other issues shown in the log.

1.) 20200127 075627 worker: Raspbian OS   (10.0)

Version 10.0 is what shipped in moOde 6.0.0. I'd recommend starting with a fresh 6.4.1 image which is based on the latest Raspbian 10.2.

2) 20200127 075629 worker: USB source (Music)
20200127 075629 worker: USB source (Music_)
20200127 075629 worker: USB source (Music__)
20200127 075629 worker: USB source (Music___)
20200127 075629 worker: USB source (Music____)
20200127 075629 worker: USB source (Music_____)
20200127 075629 worker: USB source (Music______)
20200127 075629 worker: USB source (Music_______)
20200127 075629 worker: USB source (Music________)

These ____ lines result from the USB auto-mounter unsuccessfully un-mounting the device after its removed. I'm not exactly sure how this happens. You can get rid of the orphaned mount points using the commands below.

Code:

1) Verify the directory is empty
ls /media/Music_

2) Remove it
sudo rmdir /media/Music_

# Repeat for other directories
