No, after the patch I don't need 100% anymore. The HP output is fine now, and I can tune it up and down a bit. Before using the mixer-amp, going from 90 to 100 resulted in going from no sound to little sound. Now the range is more useful. > > Takashi > > >> >> ----- >> upload=true&script=true&cardinfo= >> !!################################ >> !!ALSA Information Script v 0.4.51 >>
