Las edited 04/12/2008 soundcheck Since we're talking Audio over here, it is always best to have the latest ALSA and ALSA drivers installed. Unfortunately Ubuntu and others are far behind the most current ALSA revisions, which I'd call a major problem for us Audio freaks. If you run e.g. a ZEN Kernel (see Kernel-Wiki) you are much more up2date. However, currently even they are behind. SO - Best is if you know how to upgrade ALSA manually. I am maintaining a manual upgrade script over here at Ubuntuforums: https://ubuntuforums.org/showthread.php?t=962695 It'll be really easy going - I promise. Just try it. = 2. USB driver (snd-usb-audio) tweak (Highly recommended!) = For best audio performance on an USB port, I strongly recommend below tweak. If you run the Upgrade script, just do the download (-d option first), then edit below file and afterwards you run the script with -i option. $--------------------------------------------------------------------------------------- Patch the usb-snd-driver for people running USB-DACs $--------------------------------------------------------------------------------------- $ sudo gedit /usr/src/Alsa-1*/alsa-driver*/sound/usb/usbaudio.c $------------------------------------------------------------------------------------- # Search for "1000 * MIN_PACKS_URB," # change 1000 to 64 and save it. # On slow PCs ( such as single cores 1.4Ghz) you might need to choose a higher value then 64 - such as 120 # With my 2.16GHz Core Duo I manage a setting of 16 ( The lower the better!) $-------------------------------------------------------------------------------------- |
