Hi All! I am new to this mailing list. I was making sound for two years, then i stopped. Now I am thinking of return, but want to try the *nix platform instead. In near future, im thinking of buying new computer, so then i'll install some distro of linux. For now i was just wondering if i can hear anyone's work on linux audio apps (mp3 pref.) demonstrating the potential of linux. thanks in advance ping

[linux-audio-user] Re: Save/restore ALSA mixer settings

by David Baron

<<Two problems: 1. The original script used a syntax msg( alsactl restore ....). This does not to anything. 2. The script as I changed it with a direct call to alsactl restore is apparently no being run or being run out-of-order on startup. <<< Actually, the thing gets muted out when loging in or out from a KDE session. Not nice.

Re: [linux-audio-user] Re: [linux-audio-dev] How to automate hdsploader

by ico＠fuse.net

Thanks a lot for the help Paul! One more quick question though, has the issue with jackd + alsa + hdsp ever been fixed where jackd only allows 2 periods and no other number? Best wishes, Ico >Hence, I've been wondering what do I need to do to automate hdsploader as soon > as the cardbus has been connected? using the new modprobe.conf syntax .... install snd-hdsp /sbin/modprobe --first-time --ignore-install snd-hdsp && { /usr/bin/hdsploader; }

[linux-audio-user] Mixers (maybe)

by Laura Conrad

I had to rebuild my system a couple of weeks ago, and I'm having some trouble with sound. What I want to have work is my SBLive sound card under alsa. I did the install from a knoppix disk, and I boot it with the alsa option. I can play sounds using timidity, aplay, and realaudio (at least), and record using audacity. kmix seems to work correctly. However, when I try to run most of the mixers, I get error messages, and therefore I can't use sound apps that expect to be able to run a mixer. I seem to get all the same errors whether I'm root or a user, so I think the permissions are set up correctly. Here are some sample error messages: #pydance pygame.error: mixer system not initialized #pysol Traceback (most recent call last): File "/usr/share/games/pysol/pysolaudio.py", line 229, in startServer self.audiodev.init() error: unable to open audio: No available audio device PySol: could not connect to pysolsoundserver, sound disabled. root@tuba:/etc/init.d# ./alsa restart Storing ALSA mixer settings...failed. Starting ALSA..../alsa: Error: alsactl restore failed with message 'alsactl: load_state:1134: No soundcards found...'. done. root@tuba:/etc/init.d# [~]# alsamixer alsamixer: function snd_ctl_open failed for default: No such device [~]# [~]# amixer amixer: Mixer attach default error: No such device Does anyone have any idea what could be wrong? I've done a lot of googling, and these error messages aren't uncommon, but none of the suggested solutions seems to work for me. -- Laura (mailto:lconrad@laymusic.org , http://www.laymusic.org/ ) (617) 661-8097 fax: (501) 641-5011 233 Broadway, Cambridge, MA 02139

[linux-audio-user] Debian Unstable Rosegarden & Ardour

by David Mulcahy

Sorry for the repost - first post went a bit astray Hello all Just recently updated debian unstable and I am not sure if it was just coincidence, but if an ardour session is loaded and I start rosegarden, somewhere in the middle of initialising a session ardour gets killed. In fact it is impossible for the two apps to coexist rosegarden always kills ardour Anybody else seeing this with debian Dave Ps anybody getting debian version of jackeq to work properly?

Re: [linux-audio-user] realtime-lsm module and 2.6.9-rc3-mm3-VP-T3 x86_64: wont boot

Only a guess... Thanks for the help! I hope this enables my jackd to run in realtime without weird errors. -thewade
