Is it just me or is ALSA a little bit pessimistic about maximum gain levels for inputs and outputs. Of a sample of 3 machines (old desktop with a SB Audigy, New desktop with Intel HDA and my Fuji laptop) none of them seem capable of getting the volume out of their speakers that they were capable of in Windows. Also I am having trouble getting any of them to work with a selection of passive (and in one case a USB) microphone at anything like the input gain I need to use them with things such as skype. Is there any way to tweak the input/output gain of my soundcard beyond the limits of the mixer sliders in alsamixer ? My USB Mic is a particular problem as I can just about live with the maximum output volume. But the USB mic is part of a USB camera and with the gain at maximum I can just about be heard with everything set to max if I speak directly into the mic/camera but with it mounted where it needs to be on top of my screen I am barely audible unless I shout. Not that I think it is device specific as it seems to affect even the analogue microphone inputs but my webcam/mic combo is ID 0c45:62c0 Microdia

I think it's you. ali5451 with ALSA-Lib 1.0.15 works fine for me. I can comfortably overload the internal speakers and microphone - if it was a mixing desk, it would be red-lighting like a christmas tree. My USB Mic (yealink) was OK but I don't think it ever overloaded. [...]

Patch the driver? Icky but a last resort. File a bug? Hope you get it working, -- MJ Ray (slef) Webmaster for hire, statistician and online shop builder for a small worker cooperative http://www.ttllp.co.uk/ http://mjr.towers.org.uk/ (Notice http://mjr.towers.org.uk/email.html) tel:+44-844-4437-237

I think I may also have rubbish max gain levels with intel-hda driver. I've not really carried out any proper tests though. But you have just reminded me to look at ALSA's bugtracker, which I will do tonight. I have a vague memory of seeing some entry there about a driver having very quiet sound output, but I don't remember which driver. Thanks, Srdj
