We are using a TFA9879 with a CUI CVS-1508
We are having many audio quality problems. When the TFA is connected to a much larger speaker, it all sounds fine. We need to turn the volume way down to hear intelligible audio out of this speaker.
1. Is there any speaker specific tweaking that should be done to match the amp to the speaker (i2c regs)?
2. Where is that fancy software and eval kit shown here? ttp://www.nxp.com/video/digital-in-mono-class-d-audio-amplifier-with-feedback-loop-for-low-power-applications:MONO-CLASS-D-AUDIO-AMPLIFIER
