Still using DVTool 1.10beta 5 (latest DVTool-2.0beta4-linux did not work for me on CentOS orfedora 10), here with very good results on Fedora 10 on the desk machine, which I recently changed from CentOS 5. Latency is no longer an issue. I prefer to use the Java sound Audio Engine for output which uses the default sound device. To keep the Logitech headset as default, I use the following method, as the kde system multimedia settings, does not seem to alter the original soundcard default I had.
" Both Fedora 9 and 10 speed up the boot process by loading device drivers for hardware in parallel. If you have more than one soundcard there is an unfortunate side effect to this feature. It is not possible to predict the load order of the soundcards (ie: sometimes one card will be the first, sometimes the other). Regretfully both Fedora 9 and 10 do no longer have a graphical utility to set the default soundcard (argh). It is important to always have the same sound card order to be able to use hw:0 (or hw:1 or whatever) as the target device for starting Jack. Typing this in a terminal will show you which cards you have and what is their current order: cat /proc/asound/cards If you see just one card you should be fine and can ignore the rest of this section. Otherwise you will need to edit as root /etc/modprobe.conf (or create it if it does not exist) and add some magic so that the card device drivers are always loaded in the same order. You can use the following template as a basis for what you have to add to modprobe.conf. If modprobe.conf already exists just add to this at the end: alias snd-card-0 snd-CARD_0 options snd-card-0 index=0 options snd-CARD_0 index=0 alias snd-card-1 snd-CARD_1 options snd-card-1 index=1 options snd-CARD_1 index=1 ... alias snd-card-N snd-CARD_N options snd-card-N index=N options snd-CARD_N index=N In this template ``...'' stands for more lines here, one for each extra card (don't copy the dots! :-) ``CARD_N'' is the name of the kernel module that corresponds to the card you want in position ``N'' (N=0 is the first card, usually the default device used by all programs). If you don't know what kernel module your card uses just do this as root from a terminal: /sbin/lsmod | grep ^snd This will list all the soundcard related kernel modules. From the list and the output for ``cat /proc/asound/cards'' you should be able to figure out which is which. Here is a filled in example that includes three cards: alias snd-card-0 snd-ice1712 options snd-card-0 index=0 options snd-ice1712 index=0 alias snd-card-1 snd-ens1370 options snd-card-1 index=1 options snd-ens1370 index=1 alias snd-card-2 snd-usb-audio options snd-card-2 index=2 options snd-usb-audio index=2 As there is currently no clean way to reload the whole alsa subsystem just reboot the machine. From now on the cards you have should always appear in the same order. " My /etc/modprobe.conf reads; alias snd-card-0 snd_usb_audio options snd-card-0 index=0 options snd_usb_audio index=0 alias snd-card-1 snd_hda_intel options snd-card-1 index=1 options snd_hda_intel index=1 This works very well for me. vk4tux
