Well, position yourself with a working ardour, and then think how much time you would spend on helping others, when all that time you could be making music :) > My annoyance is when it was asked of me to provdie more information and > I did .. no response came.. then when I tried to resolve it myself and > no further response came that's when I could only put 2 & 2 together and > see that a response I made to the string "ahem" could have been related Sometimes more information does ring a bell to someone, sometimes it doesn't.

[linux-audio-user] envy24-control cannot set proper input-level for terratec ewx

by Hartmut Noack

I run Linux 2.4 / SUSE 8.1 pro on a Duron 1300 - PC with a Terratec EWX 24/96 - PCI - Audiocard. Yast2 installs Kysela`s Envy24-Control - Mixer for this Card and it works well for playing Wav/Ogg/MPEG-Audiostreams etc. BUT: to set the Inputlevel properly is nearly impossible. If a soundmessage from Bash occurs the input is distorted and set to SW-Radio - "Quality", same with other Systemmessages. To get an undistorted Signal i have to set the Input extremely low, if it is set to the same volume as the internal output (from XMMS etc) it is extremely distorted and/or i get the SW-Radiosound as described above. here my questions: 1) is there an alternative to alsa/envy24-control that works ok with EWX ? 2) is there a patch for envy24 as RPM ? thanks -- HZN/Berlin/Fh http:www.linuxuse.de

Here's what doesn't make sense to me. The Web Site that you referred me to says: "Ultra DMA modes, such as UDMA2, 4, and 5, are also referred to as ATA/33, ATA/66, and ATA/100, respectively." Now, the term "respectivly" means that mode 5 refers to ATA/100. When I look at the output of "dmesg" I see the line: "SiS730 ATA 100 controller" And yet the output of "hdparm -i /dev/hda" lists" Model=Maxtor 6Y080P0, FwRev=YAR41VW0, SerialNo=Y30HJLPE Config={ Fixed } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=57 BuffType=DualPortCache, BuffSize=7936kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=160086528 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 AdvancedPM=yes: disabled (255) WriteCache=enabled Drive conforms to: (null): 1 2 3 4 5 6 7 There's not even a listing for udma5. Since I keep reading all these warnings about not trying settings that aren't supported, should I try udma5? Just in case I missed something (and I've been reading everything can get my hands on for weeks now) here some info from my Mother Board Manual: The mainboard delivers high-level performance with support for... <SNIP> ... and two PCI Bus Master Ultra DMA (UDMA) ports that support up to four ATAPI devices. The PCI IDE also supports PIO Modes 3 and 4, UDMA33/66/100 IDE and an ATAPI CD-ROM And further into the Mother Board Manual it says: The built-in fast PCI IDE controller supports ATA Programmed Input/Output (PIO) and Direct Memory Access (DMA) mode. The Ultra DMA33/66/100 feature delivers data transfer rates up to 100 MB/s by providing a separate data path for two IDE channels and improving multi-tasking performance Thanks Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

[linux-audio-user] Seeking advice in making my app more "user-friendly"

by Ivica Bukvic

Hi all, (Tried getting some help at the LAD list but so far I got no response, hopefully I can get some input from you guys :-) -- for those who are subscribed to both lists, my apologies for cross-posting) I am in the process of revamping my app as well as adding more features. The problem my app currently has is that the main window is not resizable, which may potentially cause problems on displays with limited resolution. I've decided to fix this issue once and for all but am not sure which path to take. The app in question is RTMix and its current layout is split into two parts: Top with timers and buttons Bottom with the main notification widget and bunch of tabs for editor and other functionalities. The app looks something like this: _________ |buttons| | timer | _________ | tabs | |widgets| _________ Now I am ready to begin working on a resizable version (which should mostly not be a problem, other than being time-consuming) and am wondering whether I should separate the two widgets all together and have them therefore fully customizable (size-wise). While this option seems very easy to implement and also attractive, I am concerned with the issue that the app will easily lose its default looks and may quickly become overwhelming for the first-time user (since it is designed to provide performer-computer interface with the least amount of familiarization required). I would especially appreciate comments from people who got to use RTMix as to what would they like to see, but of course I would appreciate anyone else's opinions on this matter as well. The other option I've been thinking is to move the two widgets side-by-side, rather than having one over the other, which would certainly make maximizing window easier and would utilize the desktop space more efficiently. However, the issue is also that the app has a bunch of other deployable floating sub-windows and as such this may not prove to be the best solution, and would probably look pretty useless when having a relatively small window. Finally, I can simply leave the app as it is but then the notification interface (the bottom part) as well as other tabbed widgets of the bottom part (such as the script editor) will not be as efficient in utilizing the desktop space as they could possibly be. I also thought of having the two widgets designed in such a way that they can be "glued" together (i.e. xmms-like) or separated as needed, but I am just afraid that this option may take too much effort since then I would have to get rid of the default window decorations (in order to make them "gluable") and make my own custom-designed window handles, which seems too much of a nuisance to implement. I am sure someone might have yet another idea regarding this issue that I am simply unable to think of so I would greatly appreciate your input on this matter. The bottom line is that I am looking to make this app as flexible in terms of desktop space utilization as possible while sacrificing the minimum amounts of the "standardization" it currently has to offer. Your help is greatly appreciated! BTW I am using Qt (if that becomes relevant at some point). P.S. I have a bunch of screenshots on my site, but the network is currently screwed up on the University campus so it may end up not being available for the next 8-24 hrs. Hence, I am unable to give you the screenshots. However, you may wanna try the URL in my sig -- who knows, maybe the network will be up by the time this hits your inboxes :-).

[linux-audio-user] mkisofs ... isn't recognized on Mac

by R Parker

Hi, Maybe someone could hit me with the clue stick. Please. I have generated a data disc, comprised of audio files, using; 'mkisofs -o $FILE.iso $FILE | cdrecord -v fs=6m speed=4 dev=0,6,0 /home/tmp/$FILE.iso'. When these disks are inserted into the CD drives on Macintosh computers, they either fail to be recognized immediately or they'll be partially read but ultimately fail. Could someone please give me a clue as to what I need to do to produce a data disk/file system that Macintosh computers can read. Preferably using mkisofs and cdrecord.

[linux-audio-user] [ANN] JACK Rack 1.3.0

by Bob Ham

Hi all, New stuff. Good. * you can now use plugins with unequal numbers of input and output ports. any excess ports get exposed as extra jack ports with names like "amplif_1-1_i2", of the form "<shortened plugin name>_<rack position>-<plugin copy>_{i,o}<port>" * wet/dry controls for the output of each plugin * logarithmic controls * much more resilient file loader http://pkl.net/~node/jack-rack.html Bob -- Bob Ham <rah(a)bash.sh>

[linux-audio-user] guitar effects, distortion, amp simulation

by Raoul Bönisch

Hello! I connect my active guitar directly to my soundcard line in plug and get a great clean guitar sound. This way I can easily apply nice effects to the guitar sound. I haven't found a really great distortion effect though. Does anybody know where to get one? On http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html and http://www.ladspa.org/cmt there are some distortion effects, but I can't manage to get a great sound with them. Perhaps somebody knows the proper plugin parameters to use? The sound may not be really great because I don't use any amplifier or box simulation. How exactly do these simulations work? Where can I get them for Linux? If at all possible in form of a LADSPA plugin. Thanks for your help. ra

[linux-audio-user] ALSA Modules show status (autoclean)?

by Al Oomens

When my system first boots, alls the sound modules show (from lsmod) status of (autoclean). What causes this? I can run 'alsasound stop' and then 'alsasound start' and they are loaded fine and sound works. Also, the mixer module alsways seems to show as (autoclean) and 'unused', and I cannot use the graphical mixer to set levels etc. Any suggestions?
