[linux-audio-user] Recommendations for notebook spdif-in device

by HippiE

Hello, I am looking for a device which adds an spdif (lossless 44,1 and 48 kHz) input to my notebook (Samsung P35, Cardbus, USB2). Up till now I used (a desktop PC with) the great Audiophile 24/96 - is there a chance to plug it with some kind of adaptor to the notebook? Best regards, HippiE

[linux-audio-user] Re: Some Musikmesse 2005 videos about the Lionstracs Mediastation

This is so common problem in my Linux. Too often Xine wants dll files of MS Windows or of Mac or otherwise proprietary codecs. The format which works everywhere is the DVD-mpeg. It is then easy to burn the videos to DVDs. Has anyone a list of open source codecs?

[linux-audio-user] data management

by R Parker

Hi, With hotplug firewire drives is it possible to assign a partition label and have any drive automatically mounted at /mnt/client/partitionlabel? Then we can compare /mnt/client/partitionlabel to /mnt/raid5/clients/clientname and if clientname == partitionlabel then rsync clientname to partitionlabel.

[linux-audio-user] KDE sound question - in one device, out another

by Dave Price

Greetings, I have a working KDE desktop with two sound devices recognized and working: - An onboard soundchip (137x) with line-in, mic-in, and speaker jacks. - A set of USB soundsticks - recognized as an audio output-only device. These work fine with XMMS, mpg123, and KDE desktop sounds. Is there a simple (command-line pipe) or other way to set up an audio path which would route the line-in of the onboard chipset to the USB soundstick output? I do not ncessarily need to record the audio as it passes thru, but if that was easy to punch in and out, it would be cool. Also, can anyone suggest any pointer to docs on how to best use a two device setup like mine under KDE, or linux in genera? One point of confusion is that my (Simply MEPIS) installation gave me ALSA and OSS support, and I have no clear notion as to which to use fo what nad why... I have alway just used OSS in the past as a lot of the hardware I had access to preiously has not been well supported by ALSA. TIA and aloha, dave

[linux-audio-user] how to encode w64

by carmen

hi, im wondering how to encode several >2gb w64 files to a lossy format like mp3 or ogg this is what ive tried so far: sox: Failed reading itz.w64: Do not understand format type: w64 flac: ERROR unknown format oggenc: ERROR: Input file "itz.w64" is not a supported format ardour: plays ok, but no encoded formats available in export dialog cubase sx, wavelab, nuendo in vmware: wont launch samplitude in vmware: nothing happens soundforge8 installer in WINE: wont launch my vmware trial expired, and i didnt get to trying foobar2000 or soundforge8 in vmware, but even if they did work, the audio would have to be sent over a samba connection at a few mb/second..if samba didnt choke on the >2gb files to begin with..,. ..so hopefully linux can do this seemingly simple audio task..any ideas?

[linux-audio-user] mount question

by R Parker

Hi, Continuing the firewire HDD scenario. We're looking at a dual enclosure in order to mirror client data to a second drive. I want each drive to have the same partitionlabel i.e. "dana." If a partitionlabel titled "dana" is mounted at /mnt/client/dana and a second partitionlabel titled "dana" is inserted into the hotplug enclosure can it be automatically mounted at /mnt/client/mirror/dana? Anybody tried something like this? -Ron __________________________________ Do you Yahoo!? Plan great trips with Yahoo! Travel: Now over 17,000 guides! http://travel.yahoo.com/p-travelguide

Re: [linux-audio-user] audiophile 2496 with Fedora Core 3

by Michael Mossey

Thanks for your suggestions, everyone. Unofrtunately, I'm still having problems. kudzu is not finding by Audiophile 2496. I commented out the onboard sound stuff from /etc/modprobe.conf and /etc/sysconfig/hwconf and rebooted. I disabled the onboard sound in the bios--or rather, it wasn't clear what the bios options were, I selected "disable audio codec" which was the only audio-related option. I booted FC3. It detected "new hardware" which turned out to be the onboard sound. It did not detect the Audiophile 2496. This is an HP Pavilion computer. Any ideas at this point? -Mike < quote who="aljordan(a)maine.rr.com"> > When I installed Planetccrma, I had a the onboard motherboard sound card > working.
