Hi,
Glad to know it’s working.
For volume there are multiple controls like “PCM Playback Volume”, “Headphone Playback Volume”, “Lineout Playback Volume”.
Please note, setting maximum value to control doesn’t mean it sets max volume.
For example, for “PCM Playback Volume” value 0x3C → 0dB, 0x3D → -0.5dB and 0xFC & more is muted. That means setting 0x3C to that control sets max volume for this control.
Which mixer control and what value you are trying to set?
Please check the register values as mentioned here,
