There is usually both a master volume and also separate PCM level, so it's not surprising at all that PCM will change your sound volume. To get any sound both have to be turned up. But you can set the PCM and leave it and use volume to adjust. The ALSA mixer is a bit complicated for sure. Way too many options in there. I like simpler ones at least for regular non recording use. -- Doug
