I see, I didn't realize that the analog controls were really a more precice way of selecting the +4dB, CONSUMER, -10dB options that windows has available. That is what you are saying, isn't it? I did notice that O$$ can use a slider to do this, if a certain option is put into the options.cfg. If this is so, however, than I am at a loss to explain the behaviour that I am seeing between the different drivers. Here, I have booted and loaded Alsa from yesterday's CVS. I use arecord in a script that I call 'record', to feed my command line vu meter while a test tone is being fed to the Delta44 from another computer. In all of these examples, I have used the corresponding graphical mixers to raise input gain to the largest possible value: sine:root:toby> record | vu > /dev/null Recording WAVE 'stdout' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo WAVE file: 16 bits per sample, Stereo OOOOOOOOOOOOOOOOOOOO | | | | | < T:0.5 40% 5295 OOOOOOOOOOOOOOOOOOOO | | | | | < T:1 40% 5294 OOOOOOOOOOOOOOOOOOOO | | | | | < T:1.5 40% 5289 OOOOOOOOOOOOOOOOOOOO | | | | | < T:2 40% 5288 OOOOOOOOOOOOOOOOOOOO | | | | | < T:2.5 40% 5290 OOOOOOOOOOOOOOOOOOOO | | | | | < T:3 40% 5277 OOOOOOOOOOOOOOOOOOOO | | | | | < T:3.5 40% 5277 OOOOOOOOOOOOOOOOOOOO | | | | | < T:4 40% 5287 OOOOOOOOOOOOOOOOOOOO | | | | | < T:4.5 40% 5284 OOOOOOOOOOOOOOOOOOOO | | | | | < T:5 40% 5304 OOOOOOOOOOOOOOOOOOOO | | | | | < T:5.5 40% 5303 OOOOOOOOOOOOOOOOOOOO | | | | | < T:6 40% 5288 Now, I reboot and use O$$ drivers, changing to ecasound now (or any oss compat. players) with the same tone playing into the Delta44: sine:root:toby> record | vu > /dev/null (audioio-raw) Outputting to standard output [rw].

When booting into Window$, I am surprised to find that I get the highest level yet, with the same test tone: phase:toby:~> vu < Sound2.wav > /dev/null WAVE file: 16 bits per sample, Stereo OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:0.5 79% 20906 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:1 79% 20906 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:1.5 79% 20934 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:2 79% 20919 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:2.5 79% 20969 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:3 79% 20935 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:3.5 79% 20937 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:4 79% 20951 OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO| | < T:4.5 79% 20922 That was tested by recording a sound with soundforge, from the same test tone that is still playing, and then passing that to my VU program after booting back into Linux. So, I must say, that I am confused as to how I can get the best gain from this card under Linux, and especially, with Alsa!
