With STAC9228 codec, the digital mic connection has no hardware volume control. That's why alsa-lib provides softvol plugin to amplify in software up to 30dB. With Skype, check "Digital" capture volume. Usually it's in 50%, corresponding to 0dB, which means no signal gain/attenuation changes in software. In your case, you can raise it. But, your alsa-info.sh shows that it's already 100%, i.e. +30dB, and this is already quite high enough. Note that if you choose "hw" PCM in your Skype setup, this "Digital" volume isn't applied because "hw" means the direct hardware access. Make sure that you choose "default" PCM instead. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Not too sure kmix channels are confusing for me. J I raised all mux capture volumes however recording only works when I test with digital mic and the only if I speak too loudly. For example I spoken 1 to 5 and blowed air at mic. The only sound I got in recording was the air blow. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
