First, I'm super excited with the new functionalities that miniMad has with the version 4 of Madmapper. Audio + ArtNet is a killer feature for that price!
... but I'm facing some problems with the audio:
- The first was the output volume (now fixed): I had to enter to the "alsamix" menu through ssh to the raspberry and increase it 0dB (it was set to -20). It was almost impossible to hear with my PA system (I don't have gain control).
- But what concerns more me, and can cause me problems in my installation in some kind of "buffer size" noise, it's some kind of "cracking", like when you have the buffer of your sound card to small and some audio packets get lost. This kind of noise is very random, and the music is very important in my installation so must be heard very clear....
Any ideas on how to fix this? I have to deliver the installation in two days and I'm running out of time.
My set up is simple, a miniMad with a static IP, connected directly to an Advatek controller, sending up to 16 universes of ArtNet.
Do you recommend me to use an external sound card? Can I change the buffer size maybe? Or should I import the audio file in MP3, WAV, in mono, stereo, etc? Any indication in how to improve the issue is very appreciated!
Thanks in advance!
