It's hard to say what difference with original driver. Playback volume may depend on: - pcm and vol mixers, - ogain mixer which controls external amplifier power on/off (sometimes it may be inverted), - GPIO pins. On some systems GPIO pins control external amplifiers, but it is absolutely vendor specific and not software detectable. You can play with GPIOs using hint.hdac.%d.config device hint (look man snd_hda). > 2. the sound is regularly interrupted. i suspect an interruption problem. What you mean exactly by "regularly interrupted"? How often and for how long? If you expect interrupt conflict - todays patch version should support polling operation (without using interrupts) good enough. -- Alexander Motin
