As previously said pavucontrol to configure pulseaudio. BITD the default sound card was index 0. Which could not be overridden by some things. So re-indexing was the desired way to override things. These days most things respect the .asoundrc. And you can have a pretty short one to change your default index #. (if not using pulseaudio)
FILE: ~/.asoundrc defaults.ctl.card 2 defaults.pcm.card 2 defaults.pcm.device 0 You really only need the defaults.pcm.card # one though. The others are nice for things that change mixer levels in app or for hdmi audio out which might be device 3, not 0. Where card # is what is listed in /proc/asound/cards. YMMV. $ cat /proc/asound/cards Many apps let you override the default by parameter as well. Such as -D hw:2 for aplay. Or --ao=alsa:device=hw,2 for mpv which is a fork of mplayer(2?). With the above .asoundrc it's simpler with just --ao=alsa, or completely omit the option. Things like audacity let you select the available card under preferences. If you wish to use something other than the system defaults. - James ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
