v2mixer.livev2.comDIGITIZED as NEW VERSION
- the audio output i'm in linux, lock my sound card?
- on linux, v2mixer use the ALSA, v2mixer may(if alsa handle by other agent, such OSS, PulseAudio) lock the sound card for output, you other application(or the v2mixer) may no sound.
- so if you are use the PulseAudio, alsa-plugins is required to install, it will handle the v2mixer without lock and let you enable the volume control.
- i play the 6 channelsaudio in Editor player(the left player), It seems that some channels doesn't work?
- in short, whatever current audio output device channel/frequency/bits its,
- in Editor(the left player), always work as max of device supported, just like other video player.
- in Program(the right player), always output full channels after Effect Channel Map, if device doesn't support, ignore.
- in Exportalways work as project setting, doesn't care the hardware.
- i have 6 channels audio device, play 2 channels audio:
- in Program, depends Effect Channel Map, for example:
- map it to 2, hear stereo.
- map it to 6, hear 6 channels audio
- map it to 8, hear 6 channels, the channel 7 and 8 ignored.
- in Export, with all channels data.
- i have 2 channels audio device, play 6 channels audio:
- in Program, depends Effect Channel Map, for example:
- map it to 2, hear stereo. this is the project default setting.
- map it to 6, hear 2 channels, the channel 3456 ignored.
- in Export, with all channels data.
- Note1: output device above is after the OS mixer(included), some OS mixer may accept all Hz and any channels.
- for example, PulseAudio for Linux (with alsa-plugins, handle the ALSA) accept any Hz, 32 channels, then mixer to hardware, may 2 channels.
- but map as 6 and play in Program got unexpected result, you may don't known which part problem.
- because 2 map to 6 by v2mixer, then 6 map to 2 by PulseAudio.
- this example also happen in some mixer handle by video driver(HDMI output)
