Hi Colin, for some reason your test of alsamixertest didn't reach me the normal path, so I'm pasting it in from the archives: > Cool. Packaged up for Mandriva too now. Thanks :-) > What license do you use. > Couldn't seem to find any reference to it... It should be GPLv3, thanks for noticing. > Ultimately the results seem to indicate that "Master" is OK, > but out by a bit, Yeah, I have seen that on one of my test machines here as well, and I don't know if one should mark that as error, I probably shouldn't. I don't even know if that's a volume control or an ADC problem in that case. > but PCM is all kinds of broken. PCM is indeed very broken. I've traced it down to alsactl as well, and if the decision was mine, I would remove it right away, but upstream wasn't convinced. :-( See the long thread starting at http://mailman.alsa-project.org/pipermail/alsa-devel/2010-August/031054.html > FWIW, the testing for -18.0, expected -21.04 measure -20.03dB is all a > little confusing. When testing for -18.0, why is 021.04 expected? > Perhaps some more explanation would be nice as to why the expected > values differ from the test value. So when it did the initial testing signal, it set everything to 0 dB and the input signal received was -3.04 dB. So when setting Master to -18 dB, it expects the input signal to be -18-3.04 = -21.04 dB. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic
