Anne Well, offhand, one thing that I can think of is that there is some issue with the arts daemon and interaction with drivers on your sound card. My intermittent sound glitches seemed to get worse after enabling the arts sound daemon with the duplex functionality enabled. That is what allows multiple applications to play sounds at the same time. At the time, I figured that the sound driver didn't interact well with that functionality because the sound never had any glitches when I was using straight OSS which doesn't allow duplex activity. You might try diabling arts to see if that fixes things and if so, you will at least know the neighborhood of the error, if not the exact cause. -- Bryan Phinney Software Test Engineer Want to buy your Pack or Services from MandrakeSoft?

If that doesn't cure it I'll turn off the Start aRTs at boot. While I have been typing this a message flashed onto the screen. I only caught a glimpse, but I think it said something about soundserver, so perhaps it has just written/read the changed config file. Meanwhile, on the midi tab I have two entries.

Thanks, Steffen Anne, you might want to take a look at this: http://www.arts-project.org/doc/handbook/ I would suggest playing with latency settings in the arts control panel in KDE. That may improve things. Also, increasing the sleep time so that arts daemon goes to sleep when not in use a tad quicker might help. I am pretty sure that the noise has to do with duplex activity but if you want to run more than one sound application at the same time, full duplex is the only way to do it. -- Bryan Phinney Software Test Engineer Want to buy your Pack or Services from MandrakeSoft?

I have that box unchecked now because the noises that I was hearing on multiple application access actually got better when I unchecked that option. However, then you can only listen to one thing at a time. You might try playing with that setting to see what happens.

Setting this to one second made the delay that much shorter, so I have changed that setting ever since. I am thinking that apps that are 'arts-unaware' might benefit from this change but not sure exactly what is doing what. FWIW. Rolf That's a thought, Rolf. I'll shorten that time.

As I told Steffen, the second (selected one) looks absolutely normal, showing EMU10K1 Midi, but the first one has [EMAIL PROTECTED]@e - External Midi Port - but instead of o there is a small square. This is an Audigy Platinum, btw, in case that makes any difference (don't see why it should). I'm puzzled about this ALSA bit. Why am I getting no reference to ALSA? Any ideas? There are two different sound driver architectures for Linux. OSS and ALSA. I use Alsa because I read that OSS is older and supposedly not as good. You might be using OSS in which case, you can install Alsa and you should be able to switch over to it and your sound problems might improve. My own sound card was originally detected and set to OSS but I switched it, again because I read that Alsa was better. snip from a posting: --cut-- Philosophically (and technically) speaking, are there real advantages for me to install alsa (other than the above) when OSS/free works for me? I If OSS works for you, then no. ALSA's primary advantages are: [common] - separation of kernel and user-space code [all] - ALSA library can provide more functionality to applications (format conversions, sharing soundcard resources, dsp plugins) - benefits ALSA-native apps [alsa-kernel/alsa-driver] - better driver architecture - more shared code between drivers for different soundcards - fixes and improvements to common code affect all drivers - drivers behave more uniformly - benefits both ALSA-native and apps using OSS-emulation - support for pro-level soundcards without performance problems - for instance handling devices that only support noninterleaved buffer layout - befefits ALSA-native apps (and in some cases also apps using OSS-emulation) [alsa-lib] - better API for applications [alsa-lib] - more flexible configuration of various parameters - well-designed API for acquiring realtime status information (for various playback/capture synchronation purposes) - benefits ALSA-native apps So shortly put, ALSA provides a better framework for writing drivers and for developing audio applications. When comparing OSS/Free and ALSA from an end-user's point of view, it comes down to the quality of the drivers for the soundcard type in question, and the specific applications that are used. Some OSS/Free drivers are very good and support all OSS API features. If this is the case and all apps seem to work ok, you don't have much to gain from switching to ALSA... yet.
