[linux-audio-user] [ANN] No More Specimen

by Pete Bessman

Ladies and Gents, I can hack specimen while working full time. And, I can hack specimen while studying full time. But, and this is empirically verifiable, I can't hack specimen while both working and studying full time. And my situation is not likely to change for another year or so. What this means is that I'm just not cut out to run a project right now, unless I want to put it into maintenance mode. Really, that's where specimen has been for the past six months anyway, and I've been doing a rather piss poor job at that modest role! My efforts are better applied to tasks where smaller chunks of time can go a greater distance. I don't have any regrets --- this was my first real programming project, and I learned a lot. But the truth is that LMMS is more specimen than specimen right now, and it has an active development and user community surrounding it. Plus, I've always been a musician and an artist first, and a programmer second. All told, it's time to throw in the towel on this one. In a way, this is a bummer --- I've put a lot of sweat and tears (literally) into this project over the past couple of years, and it has come an incredible distance. But I'd be a fool to think that I'm better off keeping it afloat than making music and contributing to other projects. And truthfully, it's a huge relief to get this announcement out. A sense of obligation is what kept me from making it sooner, but in retrospect, that's pretty ridiculous. Considering that I'm an "open source, just for fun" guy, and not a "free software, as in freedom" type, it doesn't make a lot of sense to keep going when pain exceeds pleasure. This isn't the end of my open source music development, however. I hope to help take LMMS to the next level, and contribute to other projects that will help make Linux a competitor in the music industry. Things like ardour2, lash, jack-midi, vst, dssi, ladspa et al are the keys to our future in this regard. And I look forward to getting back to hardcore hacking in a few years, when I've got my life settled down and I'm not putting in 80 hours of work and school a week. Take care everybody, and may the funk be with you. -- Pete Bessman http://gazuga.net "So this baby seal walks into a club."

Gah. Good software tells the users what's really wrong and directs the user in how to fix the issue. This leads to happier users and less repeated "why doesn't this work" questions on mailing lists, irc, personal email, etc. Sampo

[linux-audio-user] Re: DVD-Audio

The matter was >discussed some time ago on the surround sound list, as the >DVD-A format is the only 'mainstream' one allowing musicians >and composers to create their own multichannel recordings. What concerns me is the output restrictions in place on *any* DVD player which supports the DVD-Audio format. As for digital outs - the industry has embraced the HDMI interface due to its HDCP compatiblility. HDCP licensees must agree to limit the capabilities of their products such that DVD-Audio is restricted to DAT quality on non-HDCP digital audio outputs and 'must design their products to "effectively frustrate attempts to defeat the content protection requirements." ' High-resolution audio can only ouput through HDCP digital outs (i.e. HDMI) or analog outs. This shouldn't be a problem for digital output, but does limit the audio receiver devices that can be used. As for analog outs, it appears they're being phased out in the newer DVD-Audio supporting players - almost certainly due to industry concerns about the "analog hole" or "analog reconversion problem". This is further muddied by the pending 'Broadcast Flag' legislation, which if approved, will require digital output protection technologies on all digital outs from HDTV signal demodulators and 'analog output must be limited to a resolution of 480p, which effectively limits sets with analog input to non-HD resolutions'. It is not clear to me at this point if this has any bearing on DVD-Audio, as it depends on what type of receiver system the player outputs to. (If anyone can shed further illumination on this subject, I'm all ears.) >But real full-spec DVD-A players are rare, and the future >of the format isn't very clear. It doesn't look like HD-DVD will replace DVD-Audio, at least w/re to high-resolution PCM, since it only supports MPEG compression. What is more the question is - is there any real market interest in DVD-Audio? It appears to be a fringe audiophile market - but it is also a *paying* one. ;) - Maluvia

[linux-audio-user] [admin] reminder: no html postings on linux-audio-*

by Joern Nettingsmeier

hi everyone! just a quick heads-up: html postings or other "enriched" atrocities are banned on linux-audio-*. unfortunately, the mailman response "message has a suspicious header" is less than helpful. if you see your postings bounce with this error, in 99 of 100 cases you are trying to send either html or binary attachments. this warning applies especially to our friends at gmail.com / googlemail.com. their web interface seems to send out dodgy mails by default. best, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 if you are a free (as in "free speech") software developer and you happen to be travelling near my home, drop me a line and come round for a free (as in "free beer") beer. :-D

Here's the strange part, this laptop only has two physical USB interfaces on the back, yet lspci reports four controllers. I don't know how to interpret this, nor determine the function of the two different drivers. -lee

Perhaps a troubleshooting guide for USB interfaces? The alsa wiki is a total mess on this subject. I don't know enough about the issue to filter out what's true and what's luck but I would like to edit that document to be more conclusive. Here's where I'm at with my setup: 1) CONFIG_USB_BANDWIDTH is not configured 2) Buggy kernel? How do I determine that? the initial test was 2.6.12.2, I am installing 2.6.15.5 tonight. 3) Device is not connected through a hub 4) the host controller is usb-uhci for controller 1, 2 and 3 then ehci-hcd for a fourth 5) I have not yet tried running jackd with -r 3. I did read that periods with an odd number are deprecated but I did not understand the reason. Anything other options I might have left out? -lee

[linux-audio-user] HOw do I connnect Demudi distro to the internet?

by baldobe

I have just installed a demudi distro but I can connect to the internet with it. I did get a DHCP error when it was installing saying that it could not sort out the network. When I try and connect it says that a connection is not found. It is trying to do a PPPoE connection whilst my router requires a PPPoA connection, I am on an ADSL broadband line. Can someone guide me thorugh whatI need to do to get demudi connected to the internet,please. I can connect via my other distros. Thanks Bal. -- View this message in context: http://www.nabble.com/HOw-do-I-connnect-Demudi-distro-to-the-internet--t121… Sent from the linux-audio-user forum at Nabble.com.

I'm sure in >the above situation very soon people would demand more software to >Linux so that people would not have to put $$$ extra to additional OS. Last time I checked, Wal-Mart was selling Microtels with Linspire preinstalled - the least expensive ones, not coincidentally. I find this encouraging, at least. >I'm toying with the idea that when a computer is tax-deductible, >the goverment pays with respect to lowest priced OS. Sadly, I don't see this changing. Government has shown no evidence of being concerned with cost - it's just good-old boys and girls in smoke-filled rooms - business as usual. (Incidently, since researching all this DVD-Audio and HD-DVD technology, I've developed considerably more insight into this issue. I've got a 'unified-field' theory about it all now - and it has everything to do with the copy protection concerns of the entertainment industry.) - Maluvia
