So my question is now, how can I use them ? I guess that I don't need them in jack, it is other meters like meterbridge or the ones in ardour. But when running alsa, nothing append with them in the alsamixer, no matter which setup I made and even when I get the sound at the output. > I don't even know what those "Multi Track Peak" mixers are for and how I can > get them to work (if it is possible). > > Switches in Playback tab: > IEC958 [IEC958 In L]: cannot test > IEC958 output [Off]: cannot test > IEC958 I [IEC958 In R]: cannot test > Deemphasis [Off]: I suppose that this is a low pass output filter > H/W [PCM Out]: I suppose that this is the input-output routing for alsa > H/W 1 [PCM Out]: idem Right : "the analog output routing for each channel. they're enum." > Multi Track Internal Clock [96000]: I put it at the same value that in jackd "> numid=2, iface=MIXER,name='Multi Track Internal Clock' the internal clock of the board. note that ice1724 has a single rate for all channels." > Multi Track Rate Looking [On]: What is this?
