The old behaviour was considered buggy: these stream controls are logically associated with a stream opened by an application, not with a particular hardware stream. > The bad thing about it is that 31,31 is a really bad setting for my > poorly engineered sound card. It distorts a lot. If the card cannot handle any loud output, then all outputs from any source must be restricted, so the logical place for lower volume would be the "Master" or "PCM" controls.
