You know more about alsa than I do. Can you, with this setup: - reduce single input streams (mute that one flash video) in volume? - can you switch between usb and internal card without restarting an application? Use case: You're playing a game, wife enters the room, requests that you put on headphones. Trivial with PA (even with USB headphones), what about your pure alsa workflow?

> reduce single input streams (mute that one flash video) in volume Not easily, as far as I know. What is the use-case for this, btw? Muting flash on sites other than youtube and the like (as youtube has a volume control for every video)? I use noscript and flashblock -- so I generally only see (hear) flash I want. > switch between usb and internal card without restarting an application? I haven't tried (no need -- I only use my dac for audio). Alsamixer allows you to set volume for each device, so perhaps one could set up a virtual device so that audio goes to both cards by default, and then you could mute one or the other there? Take a look at this thing I found: http://slack4dummies.blogspot.no/2012/02/alsa-multiple-output-multiple-sound.html http://slack4dummies.blogspot.no/2012/02/alsa-multiple-outpu... [edit: For switching outputs/cards "manually" via using separate .asoundrc files, not the guide linked above] I think restarting audio is enough (but that would typically not help for games, but should be fine for video (stop-start playback). [edit2: The app needs to close the audio device for such manual shifting to work -- YMMV] I only ended up with this after enough frustration with pa that I went and looked up how to do (basic) alsa config. The documentation could benefit from more (hand holding) guides, and a proper (g)ui wouldn't hurt. But when you see it as a list of inputs and outputs (both plugins and devices) -- slaves and masters -- most setups are possible.
