[linux-audio-user] meeting in Birmingham, UK?

by Daniel James

Are there any list members who are planning to go to the LinuxUser & Developer Expo in Birmingham, UK on the 15-16 April? If so we could organise a Linux audio get-together at some point during the event - maybe somewhere near the Rosegarden stand that I believe is going to be in the .org area. I was thinking of hosting an LAU event down here on the Isle of Wight, but Birmingham is much easier to get to for most people in the UK. Daniel

[linux-audio-user] PlanetCCRMA question

by Dave Phillips

Greetings: I want to put the PlanetCCRMA package on two new machines, each running a fresh install of RH 8.0. I'm following the instructions from the PlanetCCRMA site, but when I get to 'apt-cdrom add' I receive this error: bzip2: (stdin) is not a bzip2 file E: Sub-process bzip2 returned an error code (2) E: bzip2 failed, perhaps the disk is full Since this action is supposed to update /etc/apt/sources.list I can't proceed with the installation. Has anyone else experienced this problem ? Any suggestions for a remedy ? Best regards, == Dave Phillips The Book Of Linux Music & Sound at http://www.nostarch.com/lms.htm The Linux Soundapps Site at http://linux-sound.org

Re: [linux-audio-user] ANN: swh-plugins 0.3.7

by Jan "Evil Twin" Depner

Steve, I got it. I had to use the --enable-shared option on the fftw build. Apparently the swh plugins wouldn't link with the static libraries. I'm going to change my instructions (http://myweb.cableone.net/eviltwin69/ALSA_JACK_ARDOUR.html) to reflect this unless you have another fix.

[linux-audio-user] alsa / xmms / delta card

by John Bleichert

Hello All I've configured software apps (e.g. xmms and games like Kohan and Myth II) to play through the PCM Out channels on my Delta card, but I can't figure out how to get an audio CD to play out through the PCM Outs. I use xmms as my CD player and I think it's configured correctly (it always worked fine with my sblive). If xmms plays mp3 and wav files to PCM Out, how come it doesn't play CD audio to the same output stream? There is no CD audio header on the delta card - how do people using these cards listen to audio CDs? How do they get the audio to play via the IDE cables and not the old reliable direct connection from CDROM to sound card? FWIW I have the output plugin in xmms set to the OSS driver, which snd-pcm-oss seems to pick up just fine. Are there any ALSA cd players that can handle this? Suggestions welcome - JB ___________________________________ John Bleichert syborg(a)stny.rr.com

[linux-audio-user] alsa-lib-0.9.0rc8a --with-jack

by anton

Hi I just fetched the latest alsa release. Everything works fine. However I saw a new( I think) option for the alsa0lib ./configure script named --with-jack. Anyway as I a big Jack fan I did ./configure --with-jack (everything ok ) make gcc -DHAVE_CONFIG_H -I. -I. -I../../include -I../../include -g -O2 -c pcm_dmix.c -MT pcm_dmix.lo -MD -MP -MF .deps/pcm_dmix.TPlo -fPIC -DPIC -o pcm_dmix.lo make[2]: *** No rule to make target `pcm_jack.c', needed by `pcm_jack.lo'.

[linux-audio-user] How does one alter the main mixer volume (or any other mixer level) in ALSA from a command line (via a simple system call)?

by Ivica Bukvic

Hi all, I have this small question: Is it possible (I presume it is) to alter mixer settings in Alsa by invoking some kind of a system call using shell (i.e. how the RME hdsp can have its stuff altered)? If so, what is the range of values that describe the loudest and softest levels? Finally, are these levels standardized? Any help on this matter is greatly appreciated! Thank you! Sincerely, Ico P.S. Apologies for cross-posting.
