Hello, I got "Audio Advantage Micro" and a USB device with the C-Media chip. I would check them on recent FreeBSD-stable. I put some WAV file into /dev/dsp or use xmms, and changed volume with `mixer' command on console. They had only one volume knob, `speaker'. On windows, They look like having other knobs, but they must be software volume knobs included OS. Because FreeBSD don't have any software volume knob included OS, volume of "Audio Advantage Micro" can't be controlled without `speaker' knob on FreeBSD. Though I could control volume with `speaker' knob, it had one problem. Reasonable range of the knob was very narrow for my ears, from 0 to 8 (full range of knob is 0 to 100). If I set the knob to 9 or above, volume was too loud. <20050825195625.3661dd05.torfinn.ingolfsen@broadpark.no> torfinn.ingolfsen@broadpark.no >> A friend of mine have bought this neat little USB Audio device, called >> "Audio Advantage Micro" made by Turtle Beach. <20050826000636.545b6b8f.torfinn.ingolfsen@broadpark.no> torfinn.ingolfsen@broadpark.no >> And now the device works when I select it in xmms. >> However, the volume is very loud, so loud that I fear that my headphones >> will break.

J1116U), and theyu have the same problem. XMMS can't control volumes of USB audio devices. I guess that some audio programs (e.g. realplayer) can't control, too. (These programs try to change `main' volume knob, but USB audio devices don't have `main' volume knob. MS-Windows may force an existing knob into `main' knob.) Some programs (e.g. mplayer) don't have this problem, because they have a software volume controller. >> I tried using the mixer in Xfce4 (xfce4-mixer), but it just says that >> mixer1 has a "Spkr" output. It's correct. It is an ordinal behavior. >> What tool should I use to control output volume of this thing? At least, volume can be controlled with `mixer' command. I expect that volume can be controlled with Xfce4-mixer. Indeed, I could control volume with xmsmixer. But C-Media chip has the narrow-range problem written above, so it is defficult to control volume with GUI. So I recommend that you use some programs with software volume controller, e.g. mplayer.
