I’m trying out Ultramixer 2.3.8 and have been so far fairly impressed with the improvements, since I last tried it a while back. One thing that is broken though, is my Edirol UA-25 sound device now has lots of audio clicks at fairly regular intervals. This makes it unusable for live playback and pretty annoying for previewing. I tried ALSA as well as OSS (emulated through ALSA). I believe this device worked OK in the last version I tried, which was probably over a year ago. My laptop’s internal sound device works fine.
I tried the device at 48KHz and 44.1KHz (its hardware switchable). It uses the format S24_3LE (24 bit 3 byte little endian).
One other issue I have noticed is that the bottom line with the Menu, Quit buttons, etc is cut off about half way (so you can only see the top parts of the buttons), I suspect this is because the application isn’t going full screen (the Gnome menu is above it). I tried it at a lower resolution and it works fine.
Is there any way to reduce the CPU usage of UltraMixer? I suspect a lot of the usage is related to the display updates for the track time, since when UltraMixer display isn’t visible CPU goes down quite a bit.
Any tips would be most appreciate. I haven’t really found anything comparable for Linux, so it would be nice to be able to use this. Thanks!
