| 19:31.58 | landley | My ipw3945 driver decided that its closed source firmware was going to throw a wobbler, and it took me a while to figure out I needed to rmmod and re-modprobe it to fix it. |
| 19:31.58 | prpplague | landley: hello again |

| 20:29.20 | prpplague | quad trace oscope makes all the difference in the world |
| 20:32.13 | landley | I assume you mean learning the hardware side of audio interfacing? |
| 20:39.08 | prpplague | landley: and software |
| 20:39.12 | prpplague | landley: on a low level |
| 21:00.46 | landley | prpplague: ever since I realized how high quality an audio output you could get from a parallel cable, 8 resistors, a little solder, and an audio jack, I've been much less impressed by the entire area. :) |

| 21:02.38 | prpplague | yea |
| 21:02.44 | landley | Ever since then, I've gone for the cheapest sound card I could. |
| 21:02.58 | landley | And talked friends out of the $100 sound blaster mega-thingies with the multiple front panel knobs. |
| 21:03.07 | landley | They mostly just get in the way... |

| 21:43.34 | MonMotha | landley: you'll have trouble convincing me to give up my sound card |
| 21:43.44 | MonMotha | I think my Revolution 7.1 beats your parallel port dongle :) |
| 21:45.07 | landley | My laptop doesn't have a parallel port dongle. |
| 21:45.19 | landley | It has some really cheap crappy intel thing integrated into the southbridge. |
| 21:45.32 | MonMotha | well, yeah. Those tend to suck :) |
| 21:45.48 | landley | And if I plug expensive speakers into it, I'll guarantee it sounds better than your expensive sound card with cheap speakers. |
| 21:45.53 | landley | Spend your money where it _counts_. |
| 21:46.06 | MonMotha | landley: I have a Promedia 2.1 setup for my computer |
| 21:46.18 | MonMotha | it's tough to top that and still be in the realm of "computer speakers" |
| 21:46.44 | MonMotha | yes, if you hook a couple of JBL studio monitors up via a nice amp, you'll do better |
| 21:47.04 | MonMotha | and actually, I've noticed that laptop audio tends to be VERY noisy |
| 21:47.18 | landley | MonMotha: ok, you'e got me there. |
| 21:47.20 | MonMotha | especially when running off those cheap power bricks they come with |
| 21:47.22 | landley | The laptop audio _is_ very noisy. |
| 21:47.30 | ds2 | no sp/dif on your laptop? ;) |
| 21:47.32 | landley | (Only when it's plugged into AC, though. Running off battery, it's fine.) |
| 21:47.45 | MonMotha | landley: exactly. It's usually cheap power bricks and lack of filtering |
| 21:48.05 | MonMotha | though I've found that on some laptops I can hear activity on certain busses and/or to certain devices |
| 21:48.16 | landley | Actually it's the components being crammed right next to each other so the electromagnetic interference causes detectible currents in the audio output jack itself. |
| 21:48.24 | MonMotha | usually things like power transients, not actual signal coupling, but same problems |
| 21:48.38 | landley | The power plug and the audio jack are right next to each other. Not a whole lot you can do about that one with filtering... |
| 21:49.08 | landley | I can reduce the noise slightly by holding the cables away from each other. |
| 21:49.12 | landley | Not really worth it. |

| 21:49.24 | landley | I can only tell there _is_ noise when I've got my noise cancelling headphones switched on. |
| 21:49.37 | landley | And only on quiet signals. |
| 21:49.57 | ds2 | use SP/DIF |
| 21:50.07 | landley | ? |
| 21:50.08 | ds2 | I doubt the power transient has optical components |
| 21:50.18 | ds2 | SP/DIF is an optical audio interface |
| 21:50.25 | landley | Ah. |
| 21:50.45 | landley | I'm working with my existing laptop hardware, which was chosen based on being cheap for the processing power. |
| 21:50.59 | ds2 | oh |
| 21:51.02 | landley | Next one I'm going to insist the darn bluetooth works, I expect. |
| 21:51.28 | ds2 | wonder if you could just use a USB dongle for audio output to improve quality |
| 21:51.51 | landley | The linux bluetooth system gets very unhappy if your bluetooth thing is a USB dongle, and you hot-unplug it. |
| 21:52.03 | landley | ds2: possibly. It'd stay digital longer. |
| 21:52.19 | landley | But the USB audio spec has all sorts of content restrictions management crap in it, I've never wanted to go there. |
| 21:52.21 | landley | I'll take the buzz. |
| 21:52.49 | ds2 | landley: plus you would probally benefit from possibly 2 more layers of power filtering (LDO on the dongle + whatever is on the USB power from the laptopside |
| 21:53.04 | ds2 | I have been able to get away with a hot unplug |
| 21:53.18 | ds2 | of a BT dongle... hcid eventually recovers |
| 21:53.20 | landley | ds2: oh I've been able to get away with it too, some of the time. |
| 21:53.38 | landley | And other times, the bluetooth subsystem panics. (Not a bad panic, but a "not going to work again until you reboot" panic.) |
| 21:53.56 | landley | The track mentions lots of bluetooth functions. |
| 21:54.13 | landley | And then the SMP locking gets all funky. Resoucres do not get freed right. |
| 21:54.23 | landley | The kernel basically washes its hands of the entire subsystem. |
| 21:54.26 | ds2 | does it mention something about URBs? |
| 21:54.33 | landley | I forget. |
| 21:54.43 | landley | I could plug it in and unplug it a half-dozen times to see, but I'd rather not right now. |
| 21:54.49 | ds2 | :) |
| 21:55.01 | landley | Maybe it's fixed in current kernels, this is the Ubuntu 8.04 stock kernel. |
| 21:55.09 | landley | They've screwed stuff up before, and it's not cutting edge... |
| 21:55.30 | ds2 | what 2.6 version is it? |
| 21:56.38 | *** join/#edev CosmicPenguin (n=nobody@163.181.251.103) |
| 21:56.39 | *** mode/#edev [+o CosmicPenguin] by ChanServ |
| 22:16.26 | landley | ds2: 2.6.24-19-generic |
| 22:16.36 | landley | It's an ubuntu custom version based on .24. |
| 22:16.51 | landley | So maybe 9 months out of date now? |
| 22:17.59 | ds2 | Hmmm |
| 22:18.19 | ds2 | .24, IMO is not that old |
| 22:18.31 | ds2 | but then I prefer stable systems over new features |
| 22:18.33 | CosmicPenguin | three versions |
| 22:19.03 | ds2 | I still consider 2.4 viable ;) |
| 22:19.16 | landley | ds2: it's old enough that asking the list about a kernel panic is unlikely to garner much attention. |
| 22:19.28 | landley | 50% chance they've already fixed whatever the underlying issue is. |
| 22:19.49 | ds2 | *nod* |
| 22:20.00 | ds2 | shouldn't be that hard to debug it |
| 22:20.14 | ds2 | the bluetooth stuff seems reasonably well mannered |
| 22:20.23 | landley | Yeah, but it may not happen in a vanilla kernel at all. |
| 22:20.50 | landley | But installing a vanilla kernel on this box means getting all the hardware working (including the ipw3945 network card, which is a pain). |
| 22:21.12 | landley | Not impossible, just enough of a pain that I generally don't bother after I upgrade... |
| 22:21.20 | ds2 | hugs his atheros network card |
| 22:21.38 | landley | I have lots of experimental systms. My laptop is not one of them, I generally just want it to work, and don't fiddle with bits that currently work. |
| 22:24.29 | ds2 | what do you currently use bluetooth for? |
| 22:32.37 | landley | ds2: I can get internet through my cell phone. |
| 22:32.50 | landley | Well, I could before it broke a couple weeks back, but that's t-mobile's fault. :) |
| 22:33.14 | ds2 | datacard ;) |
| 22:33.20 | ds2 | eliminate the BT |
| 22:33.20 | landley | When it works, the modem acts as a bluetooth serial device that you can ppp through to talk to the internet. |
| 22:33.30 | landley | Actually usb cable. |
| 22:33.35 | landley | I've got one on order.. Probably in by now. |
| 22:33.45 | ds2 | I know, I use the exact same setup but not on the main laptop cuz I don't want no protruding dongle |
| 22:34.34 | ds2 | does TMO carry a phone that works well for BT tethering? (well as it the BT doesn't cause periodic crashes when the phone goes out of a service area) |
| 22:37.10 | landley | I've got a t639 and it seems to work here in Austin, and in NYC. (Well, when it's not broken.) |
| 22:37.17 | landley | Samsung t639. |
| 22:37.36 | landley | As for crashes, that's presumably the bluetooth layer's problem, not the phone's. |
| 22:38.25 | ds2 | I am doing this with a Treo 650 |
| 22:39.05 | ds2 | the crash is from trying to establish a connect w/o it being in DUN mode; but there is a bug where if you loose coverage, it drops out of DUN mode automatically but doesn't change any of the icons |
| 22:53.24 | landley | Fun. |
| 22:53.34 | landley | I have to go pick up Fade from work now, though. |
| 22:53.57 | landley | All I can say is it worked with Ubuntu 8.04 and a samsung T639, until it suddenly stopped working due to the samsung phone hanging up instead of finishing the PPP session. |
| 22:54.04 | landley | I think the config on their end got screwed up, mine didn't change. |
| 22:54.18 | landley | Called their tech support twice and got two different suggestions, need to follow up but I've been busy... |
| 22:54.44 | ds2 | haha... did they kick you up to the next level support in either case? |
| 22:54.48 | ds2 | bah |
