I sometimes have similar issues, but I'm pretty sure it's only been when my machine was locking up (bad RAM issues) and the alsasound init script didn't get a chance to shut down cleanly and do it's alsactl store to save the settings. When I got the box back up I would be surprised for a moment that the settings were where I left them. But, your problem sounds like a different issue. Which version are you using? I usually just have jack running in full duplex, so I haven't seen anything like that. -Eric Rz.

I bought the audiophile because it is high quality, and has hardware monitoring for zero latency. mostly based on reading archives of this list :-) But i haven't really found any docs on how to use this setup, so i am figuring it out on my own. I go into ardour (which is very cool, but also very complex for someone like me who has never done recording before) and turn on the "hardware monitoring" option. i also have h/w monitor turned on in qjackctl. When I do this, things stop making noise unless i pipe them directly into the digital mix in envy24control. a little awkward, but it would be ok if the settings in envy24control didn't change themselves. so what i would like to know is, does anyone have a doc that explains how to configure ardour, jack, and the envy24control to work together? at least, if someone could explain to me here how they work with a setup similar to mine. i see lots of posts saying "use envy24control", but they don't explain what to do with it. i could use someone with a bit of experience to help me up the curve, and if someone can do that i would gladly write an envy24/jack/ardour howto.

I'll try to answer these questions at home tonight while sitting in front of my audiobox. I could try to answer from memory .... but it wouldn't be much use to you I'm afraid. 8-) I think the thing that helped me most was reading through the manual for my card and matching up the capabilities described with the controls in envy24control. -Eric Rz.

luis jure wrote: Ok, first let's make sure we're both looking at the same (or at least similar) picture. In envy24control I have 5 tabs: "Monitor Mixer","Patchbay/Router","Hardware Settings","Analog Volume" and "About". "About" isn't very interesting. "Hardware Settings" I never need to mess with, so I don't have much to say. I think it mainly applies if you're connecting some external digital device via S/PDIF. I don't have any other digital gear so I don't need to mess with this part. The thing that most confused me at first was that the Mute buttons and volume sliders on the "Monitor Mixer" page only affect the actual audio output if "Patchbay/Router" strips are set to "Digital Mix" even though the level meters continue to function. The sliders and mute buttons are for controlling levels in the mixer on the card. If the "Patchbay/Router" strips are set to "PCM Out" or "H/W in" you are bypassing the card's mixer. PCM Out's are channels for your audio applications to connect to. They are "Out" from the perspective of the app. H/W in's are just that, inputs from the audio card hardware. Selecting these in the "Patchbay/Router" gives you direct monitoring of the signal going into your hardware. As with the PCM's selecting them in the "Patchbay/Router" bypasses the card's mixer. It depends. You can directly monitor the hardware inputs as described above by selecting them in the Patch Bay. In this case you have no software control over levels. For instance, I have my guitar plugged into H/W In 1. With the "Patch Bay/Router" strips "H/W Out 1 (L)" and "H/W Out 2 (R)" both set to "H/W in 1" I hear the guitar coming out the speakers and see the level meters respond in "Monitor Mixer". However, the sliders and Mute buttons do not affect what I hear even though they do affect the "Digital Mixer" as displayed in the level meters on the far left. I can't hear the changes because the mixer is bypassed. If I set the "Patch Bay/Router" strips "H/W Out 1 (L)" and "H/W Out 2 (R)" both to "Digital Mix" I can still hear the guitar, but now the controls in "Monitor Mixer" for "H/W in 1" do control the level I hear. Now, to answer your question, if you leave things like this (patchbay set to Digital Mix) you shouldn't have to change the patch bay to switch between monitoring input and playback. You may need to adjust the sliders in "Monitor Mixer" because now your audio will be coming from your app on the PCM Out's through the mixer on the card. If you want to bypass the mixer to monitor the inputs directly, or monitor playback directly from the PCM's then you need to change your routing in the patchbay. In the "Analog Volume" tab the "ADC x" sliders control your anolog to digital converter levels. likewise the "DAC x" sliders control your digital to analog converter levels. I always leave my DAC an ADC sliders for channels 0 and 1 all the way up. (not sure if that's correct audio-engineering-wise, but it works for me.) If you need more gain at this stage the "IPGA x" sliders will give it to you. My guess is that it would be better to get a hotter signal in rather than use these, though. I think the card's mixer outs go straight to the DACs. As far as my understanding goes, the mixer doesn't present any outputs to applications ... I think what you want has to be done at the application level. For me, that means using jack. Maybe there's some sort of .asoundrc magic that could make it happen for you. I have yet to grok anything more than minimal usage of that though. Heh. :) I feel like I maybe should have just written a tutorial. Anyway, I hope this helps. I need to get to bed now. Good luck. -Eric Rz.

Audiophile 2496 has only DAC 0 & 1, Delta 1010LT has those ADC / DAC x sliders plus IPGA (or something like that) Those control the real analog outputs. Audiophile 2496 doesn't have sliders to control the input volume. If you want to control it with the envy24control (or alsamixer), you have to record the Monitor Mixer (channels 11 & 12), but I'd recommend turning the volume up/down from the source. If it's too loud, the mixer can't 'unclip' it. Tommi
