Re: [linux-audio-dev] announce list policy question
hi jorn, thanks again for all of your effort. it means a lot to all of us! i do have one final objection to cc'd mails, that threads that span multiple mailing lists are rather irritating ;) -- i'd imagine your message, if it gets replies, will fall into that category. many folks are subscribed to more than one of lad, lau, and alsa-devel, and now possibly laa. i'd really rather not get the same message three times, even if it is a really cool project ;) On Mon, 29 Apr 2002, Joern Nettingsmeier wrote: > if i there are no other votes, it's 2:1 against cc:ing, and i lose > :) it doesn't matter a whole lot either way, in the grand scheme of things. cheers, wingo.

[linux-audio-dev] announce list policy question
hi everyone ! i'm about to announce the new linux-audio-announce list to other related mailing lists (alsa, lkml) and news site maintainers. there is this one undecided issue whether to cc: LAD/LAU on all announcements or not. i'd welcome your opinions before i make the list known to a wider audience. below, i have quoted some contributions from andy, steve and me for your reference. if i there are no other votes, it's 2:1 against cc:ing, and i lose :) best, jörn I wrote: > Andy Wingo wrote: > > > A question, though; I note that there is now an -announce list.

PD on Solaris probably is some work, as Solaris isn't officially supported by PD at the moment. Getting it to work on OS-X has a higher priority right now and on Linux PD is running just fine. ciao, -- Frank Barknecht _ ___footils__

Ok, there are several criteria to consider for sizing batteries: 1.) Required voltage. What voltage is needed? If this is going to be driving an inverter, 12V is typical. 2.) Required current. At the required voltage, how much current does the PC draw? This is necessary for the next criterion: 3.) Required battery run time. How long do you want the battery to provide required voltage at the required current? Battery capacity is rated in ampere-hours (AH) -- suppose your PC draws 5A at 12V -- and you want to run 10 hours. 5x10=50AH. That is a little larger than a motorcycle battery. My Sony Vaio notebook has twin 3000mAH Li-Ion batteries. It runs for about 2.5 hours. This means it is drawing 6000mAH/2.5H= 2400mA=2.4A. Of course, the Li-Ion discharge curve being what it is, this is approximate at best. 4.) Charger ratings. The larger the battery in AH, the beefier the charger needs to be to charge it is a reasonable amount of time. I designed a battery system for our studio here. The requirements were: 1.) 12V for inverters (StatPower ProSine 1800 x2) 2.) 24 hour run time. Experiments concluded that the Prosine 1800's could reliably start and run about a 1000W load (monitor turn-on current surges will cause the inverter to drop out -- I measured the surge load of this 1KW average load as being about 2700W, which is within the 1800's 2900W peak rating). With a 1000W load and 12V, they draw right around 90A. To get 24 hour runtime, we need 90x24=2160AH of capacity. Fortunately, the 1000W is the designed largest load -- they typically run about 70A. Now, the local telco was needing a place to off-load some large flooded lead-acid cells rated 2320AH. We were able to get them donated. With the voltage drops in the wiring taken into account, we have about 24.2 hours runtime at an 80A load -- which is a little less than what I wanted, but good enough at this point in time. I just have to keep my inverter loads around 850W or so. At which load the Prosine 1800's are very happy. Now the chargers became a major problem. At 2320AH, you need 232A to recharge in 10 hours, which is the recommended rate for these cells. Well, I couldn't afford the real telco chargers necessary for such. So I compromised -- I get a 36 hour recharge rate by using a pair of 100A rackmount 13.8V regulated power supplies made by Samlex America. These supplies, with the resistance of the wire to the batteries, level off at 100A fo the first couple of hours, and then begin to taper the current down afterwards. A full equalizing charge requires 150 hours, but that's OK. Hope that helps. -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

You can do this easily with ALSA. Its just one of the standard IEC958 bits that can be set with alsactl, amixer or set. You'll have to ask on alsa-devel what to set, since the Hammerfall driver shares generic ALSA code to set these bits, and I don't know how this is designed. There are several IEC958-related switches, and one of them contains the relevant bits for this task. However, I have no idea how you would deliver AC-3 to the S/PDIF channels. Presumably, AC-3 is a stereo (or more precisely, 2 channel) encoding of a multichannel signal, and thus its first packaged into a 2 channel form and just written to the channels. Right? --p

Neither:) I want to build a pc that functions in the same way that a notebook without a monitor would. I am wondering if anyone can tell me how I can deduce the correct power rating for this machine so that I can design a battery pack that will power it efficiently.
