| 17:38.48 | pcercuei | larsc: I heard you have a Nanonote and like to build Linux kernels |
| 17:45.40 | larsc | don't trust the rumors |
| 17:45.50 | larsc | need to go buy milk, shops close in 15 min |
| 18:08.36 | pcercuei | there's no rush |
| 18:12.24 | *** join/#qi-hardware fengling (~fengling@58.135.95.136) |
| 18:14.18 | eintopf | wahhh no milk |
| 18:14.36 | eintopf | no shoko milk :( |
| 18:19.00 | larsc | pcercuei: I'm back btw. |
| 18:25.46 | eintopf | larsc: do you will be at elce? |
| 18:26.26 | eintopf | larsc: the linux sound architecture stuff (ALSA) is so 1990 years style :-/ |
| 18:26.36 | larsc | I'll be there |
| 18:26.43 | larsc | ALSA is super advanced |
| 18:26.57 | eintopf | (be there) ah, ok. |
| 18:27.13 | eintopf | yea but to make some modern stuff people adding new layers in userspace |
| 18:27.18 | eintopf | e.g. pulseaudio |
| 18:27.46 | eintopf | using plain ALSA -> you don't like to do that anymore |
| 18:27.51 | larsc | ALSA at the core is like Vulkan |
| 18:28.16 | larsc | difficult to use for endusers, but can deliver maximum performance |
| 18:28.20 | eintopf | the new open 3d api stuff? |
| 18:28.23 | larsc | yes |
| 18:28.39 | larsc | come to my talk and you'll learn all about it ;) |
| 18:29.02 | eintopf | oh I don't know if I will be at ELCE |
| 18:29.12 | eintopf | but I recently wrote some DSP plugin |
| 18:29.17 | larsc | pulseaudio is the hero though we all needed |
| 18:29.18 | eintopf | for the alsa API stuff |
| 18:29.24 | eintopf | ladsp |
| 18:29.29 | eintopf | or something like that |
| 18:29.41 | eintopf | don't remember the name |
| 18:30.00 | eintopf | but it was funny, I had some wine plugin wrapper loader for winamp DSP plugins |
| 18:30.15 | eintopf | and feed ladspa(I think that was the name) with that |
| 18:31.43 | eintopf | I think ladspa is already deprecated? |
| 18:33.08 | larsc | I've never heard of it before, no idea |
| 18:33.33 | eintopf | ah, ok. |
| 18:34.07 | eintopf | I looked for an easy way to add some DSP for a pulseaudio output |
| 18:34.56 | larsc | I think pulseaudio has a nativ API for that |
| 18:35.18 | eintopf | yes |
| 18:35.32 | eintopf | you can load some ladspa plugin (so far I understand) |
| 18:35.34 | eintopf | http://bs2b.sourceforge.net/ |
| 18:35.42 | eintopf | I tried that at first |
| 18:35.49 | eintopf | but this is only some other technique |
| 18:35.55 | eintopf | http://www.mhampicke.de/artikel/view/17 |
| 18:36.03 | pcercuei | < eintopf> using plain ALSA -> you don't like to do that anymore |
| 18:36.08 | pcercuei | nobody ever used plain ALSA |
| 18:36.19 | pcercuei | you used libasound, aka the user-space part of ALSA |
| 18:36.20 | eintopf | that's the dsp plugin for pulseaudio |
| 18:36.28 | pcercuei | which has always been a terrible pain in the ass |
| 18:36.32 | pcercuei | for devs, at least |
| 18:36.49 | eintopf | pcercuei: the kernel part is ALSA, but userspace part can also be ALSA |
| 18:36.55 | eintopf | and yes I think it's libasound :-/ |
| 18:37.03 | pcercuei | PulseAudio replaces libasound, and that's a good thing |
| 18:37.18 | pcercuei | IMHO |
| 18:37.20 | eintopf | but I need to run pulseaudio in userspace :( |
| 18:37.26 | eintopf | I don't like to have latency |
| 18:37.32 | pcercuei | well, you ran libasound in user-space before, right? |
| 18:37.40 | eintopf | I think so, before |
| 18:37.46 | eintopf | I also used some time ago OSS |
| 18:37.54 | eintopf | and not ALSA |
| 18:38.09 | eintopf | and yes I used OSS when OSS was not in kernel anymore |
| 18:38.29 | eintopf | but OSS, the name is open sound system |
| 18:38.32 | eintopf | but it's not open :( |
| 18:39.53 | eintopf | https://fiio-shop.de/dac-mit-kopfhoererverstaerker/110/fiio-e10k-olympus-2 |
| 18:39.59 | eintopf | that's my current soundcard |
| 18:40.06 | eintopf | and I am very happy with this device |
| 18:40.57 | eintopf | there are no noising when I change the volume, not so much complicated mixer settings... |
| 18:41.01 | eintopf | I had a emu10k1 before |
| 18:41.48 | eintopf | it worked well as well, and I know the emu10k1 chip has some hardwaremixing stuff feature - I think I never get this feature running |
| 18:42.03 | eintopf | and some in-hardware effects stuff |
| 18:42.14 | eintopf | emu10k1 is okay... |
| 18:43.03 | eintopf | the fiio stuff is geat, I can also plug it into my notebook |
| 18:44.04 | eintopf | but digital coax output, I have now a converter from digital coax <-> digital optical |
| 18:44.07 | eintopf | ... |
| 18:46.02 | eintopf | I am interessted in ALSA kernel stuff, because you really need to know how doing things fast |
| 18:46.23 | eintopf | otherwise somebody will replace ALSA with a faster alternative ;-) |
| 18:46.40 | eintopf | and what about real time linux + ALSA real time use-cases |
| 18:48.50 | eintopf | larsc: I really don't like LF conferences, this is all too much marketing stuff and LF is far away from the community |
