> equivalent to setting it to ~10% on Windows. > The issue I have with this patch is that setting my volume to 100% is (In reply to Jason Pleau from comment #24) So these changes actually somehow disable PCM volume control for the gamecom 780 and only allow a very small range of reasonable values. this area of the pulseaudio master volume control corresponds to the PCM range. below this area volume control works fine. so a smaller dBmin value means a larger area in the volume control sliders which is not usable. With the parameters provided i still can use pulseaudio to get full control of the headset volume.Īs a side effect the dB range determines an area below 100% in the volume control sliders of pulseaudio for which the slider has no effect. it only changes the volume in a very small lower spectrum of the headset (which actually corresponds to normal loudness). However, with a max raw value of something like -9100 (instead of 0, which is insanely loud) and a min valeu of -9200, the PCM volume control no longer works i.e. so it was not possible to find a range which delivers a smooth transition from silence to normal loudness. Raw values of about -9100 deliver normal loudness, values at -7000 start getting too loud, values below -9200 are silence. i dont know if some of these devices work correctly. There is something wrong with the firmware of the gamecom 780. With your patch the following heuristic settings deliver a good volume 'range' and usable volume control sliders with pulseaudio.
