[linux-audio-user] Jack: renaming audio-ports?

by Julien Patrick Claassen

Hi all! Does anyone know if I can rename audio-ports connected to jack? I'm running fluidsynth and it create: fluidsynth:left, fluidsynth:right. But I would need fluidsynth:out_1 and out_2. Is this possible with the console-tools only, because I CAN'T use any GUI? Thanks for any help.

[linux-audio-user] xinerama and alsa problems

by Arthur Moore

I'm using xinerama with two nvidia cards and I'm having a problem when trying to play sound. When I stretch an app (like audacity) over two screens I get all sorts of distortions. Actually whenever any sound app is on the second screen I have problems. Like a clicking. Anyway I'm using Debian unstable, with kernel 2.4.20 (no patches), Xfree86 4.2.1, and alsa 0.9.2. Anyone else seen this problem? Art

[linux-audio-user] render soundfont performance of midi data to file?

by Will Benton

Hello, Is there some program that will render a soundfont performance of a standard midi file to WAV? Ideally, I'd also like it to provide some way to map MIDI channels to soundfont files/instruments, but a configuration file is great for that. thanks, wb -- Will Benton willb(a)acm.org

[linux-audio-user] external sound card

by Jan Stary

Hi, as my Acer Laptop only has a via ac97 chipset and one mono (mic) input and one stereo (headphone) output, I consider getting some additional hardware. I have two USB ports and a PCMCIA Card slot. Which one is better to use as a sound input/output? I mean sound quality and latency. I am running ecasound on top of alsa 0.9.2 and the 2.5.66 kernel. Any suggestions for a particular card/device/setup? Thanks a lot. Jan

[linux-audio-user] fluidsynth sound breaks on disk/cpu intense operation

by Mikhail Ramendik

Hello! Well, I finally have fluidsynth running on alsa. The 'not starting' problem was solved with getting the right version of alsa-lib; the 'no MIDI input' problem goes away by 'aconnect 64 128' when fluidsynth is already running. But, even though I run it as root, fluidsynth's sound still audibly breaks on a cpu/disk intensive operation - I tested it with starting OpenOffice and with running sxid. Is there any way to fix this? And should I try installing Timidity for such cases? I just want the synth to work in parallel with regular work. -- Sincerely yours, Mikhail Ramendik
