=== alcides is now known as Guest6800 [05:11] OK, plugging in the power supply didn't work either. Also tried from the LiveCD. Now suspecting the cable, but I've put in an order for a USB 2i2 rather than play this game for much longer. [08:12] E:The package linux-image-4.2.0-32-lowlatency needs to be reinstalled, but I can't find an archive for it. === lucius is now known as render_minde === erick is now known as Guest92321 [17:46] Hi, [17:47] I have a some easy questions about sound system in linux. [17:48] I know that for some people if they have high end video card, but they do not play game on linux. [17:49] They would install "compriz", so that they can use video card to the full potential. [17:50] While using the OS, that is. [17:51] Now, my question to you is, for the high end sound card, however, do we have something similar to "Compriz"? [17:51] Guest92321: Jack? [17:51] ]It depends on what you are doing. [17:52] Ardour now can use LASA directly. The main thing is to not use pulse for low latency audio... or really anything where you want all the samples to show up on the output that got to the input. [17:54] Low Latency is important for live use such as guitar(or other) effects and softsynth use. It is only important for recording if you are trying to get the DAW to provide monitoring of mic inputs or softsynths. [17:55] It is quite common to record at a lower latency and mixdown at a higher latency. [17:56] But, I heard "Jack" using PC resource very low. [17:57] low latency for desktop use (skype for example) is 30ms, for live use low latency is less than 10ms (round trip) streaming am mp3 in contrast is 300ms at least. [17:57] I do not understand that last comment. [17:59] Guest92321: I do not understand ""Jack" using PC resource very low" [18:01] Also, what do you mean by a "high end sound card"? ($500 or $5000) [18:02] In my opinion high end audio interfaces start around $1500 and go up. [18:03] Here is an example of my high end sound card -> https://jet.com/product/detail/41902726b2ad4b51ada8707ca265b2b5?jcmp=pla:ggl:gen_electronics_a1:electronics_accessories_cables_a1_other:na:na:na:na:na:2&code=PLA15&ds_c=gen_electronics_a1&ds_cid&ds_ag=electronics_accessories_cables_a1_other&product_id=41902726b2ad4b51ada8707ca265b2b5&product_partition_id=161710082700&gclid=CMSolfCRgswCFdgBgQodCtAGnA [18:03] (the same thing could be said for high end video controllers I guess) [18:04] What makes that high end? [18:05] It used to be super expensive sound card compare to an old PCI ones. [18:05] old PCI ones have been over $1000. [18:06] check the original price for the delta 1010 (not LT) [18:06] look at any of the audio science or RME cards [18:07] A sound blaster anything is a little better than internal HDA audio, but I wouldn't use it for recording. [18:08] http://www.esi-audio.com/products/juliaxte/ is better for example. [18:08] Still not high end though. [18:09] For desktop use, a sound card is a sound card. It depends on what you want to do with it as to tweaking will help. [18:09] I see. [18:10] The sound card that you have just showed. May I ask what it can do, beside gaming? [18:10] In general, I have found internal outputs are reasonable, internal inputs are not usable for more than phone work. [18:11] The julia? it can be used for multitrack recording. It has proper ballanced i/o at proper (+4dB) input and output levels. [18:12] It has connectors that can handle some use so far as connect and disconnect. [18:12] Would someone use it for gaming? [18:12] It is syncable to another card for expansion. [18:12] I see. [18:14] I have no idea about game playing. Why would you ask this on a Multimedia creation distro support channel? [18:16] I just want to see if anyone would use one for gaming, and what would be the benefit of it. [18:16] The sound quality/handling will be determined in a game more by the games developer than any other factor. [18:16] I see. [18:16] That is true. [18:16] If the dev knows what they are doing it will work well otherwise not. [18:18] low latency for a game that runs 25fps is quite high anyway (~ 40ms) and so should not difficult for even a 10year old computer to deal with. [18:21] One more question, please. Does Jack use more resource than Pulse audio? [18:28] I also heard that alsa is better than pulse audio. [18:28] How, though? [18:30] pulse audio is a layer on top of alsa (as is jack) that does mixing, saple rate change as required etc. Pulse does not really allow the user to do routing or set latency. [18:30] How do you change Ubuntu Studio to use "Jack" since I see pulse audio all over the place. It is defaulted in VLC too :) [18:31] in a case using pulse running into jack where jack and pulse are forced to the latecy, I have found that pulse uses about double what jack uses at any particular latency. [18:31] If, for example, VLC uses Jack, it would sound better for movie right? [18:32] it should make no difference. [18:32] pulse will try to open the sound card at the SR of the media for the first client to connect. [18:33] VLC videos are not looking at low latency because it is decoding a compressed file. All that matters is that the audio and picture are in sync... or close. [18:34] most compression does sample rate change internally of some sort anyway. [18:35] In general the external analog circuitry between the DAC and the speakers would make more difference in sound quality. [18:37] Let's say I am not a sound professional, but I want to make watching movie a better experience. [18:37] What should I do? [18:38] Like I said earlier, someone who doesn't play games, he/she uses Compriz to make OS looks much better. [18:38] I good start might be to find out what things you don't need to worry about [18:39] there are a lot of things that are advertizing gimics. A good place to start is watching: https://xiph.org/video/vid2.shtml [18:39] If I am not a sound professional, what I can do to make my OS sounds much better for music and movie. [18:40] Do you have something similar to Compriz? [18:41] probably not much. With sound spend all the money you have on good speakers, buy an amp from the goodwill store for $30 or so. [18:42] in general we do not want to colour the sound in the same way the Compriz colours video. The difference between video and audio is that all video is compressed in some way and is therefore lossy, we can easily have uncompressed audio and have been able to do so for many years now. [18:43] Salve [18:43] Ho un problema con l'installazione di US [18:43] 15.10 [18:51] I see. [18:52] Let's try one more example. [18:53] I bought a brand new sound card, and it came with a software called "PowerDVD". [18:54] My friend said without this "PowerDVD" software, you can't really benefit from this sound card when watching movie at all. [18:55] Is that really true? [18:55] I think so. [18:55] in others probably not [18:55] have you heard a difference? [18:56] Yes, I can hear the differences. [18:57] I am trying to look it up to see what it is. [18:57] If you use VLC instead, VLC would sound a lot worse. [18:58] VLC will not use this sound card to the full potential. [18:58] full potential? in what way? fewer channels? [18:59] To make movies sound much better that is. [18:59] how? [19:00] I go to the Cyberlink website and they have powerdvd. I am not seeing anything on how it may make things better. [19:01] I think the developers from "PowereDVD" would care about sound more that VLC. [19:01] If that was true they would also be proud to tell us what they do to improve sound. [19:01] They do not. [19:02] The same example when you mentioned game developers earlier, maybe :) [19:03] when I see statements like "Next-generation smart TrueTheater enhancements provide a truer-to-life media audio-visual experience" I want to know more details, but there are none. That line is just advertizing copy. [19:03] I wonder if these enhansments are anything more than changing the eq. [19:05] I know. [19:05] so far as I can tell all it does is decode the sournd already on the DVD nothing more. [19:05] They must have change the eq for you. [19:06] Right. Right. [19:06] It may be that VLC, mplayer, etal just need the right codec to do the same thing. It may even be available. [19:07] I see. [19:07] I see the term H.264 encoding and decoding for example. [19:08] I see. [19:09] They use something like encoding and decoding. [19:10] comercial DVDs all use proprietary encoding any more. Not because it is better quality, but so they can control who plays it on what. [19:14] anyway, I am away for a while. Talk to you later. [19:14] Thank you. [19:17] One more question for anyone who is around. [19:18] Let's say I bought this new sound card, which has these technologies on the front of the box. [19:22] THX, 3D Surround Sound, and DTS. [19:23] How do I use such technologies in Ubuntu Studio? [19:24] Or what I have to do in order to not forget to use ones. [19:24] :) [19:25] Do you think Ubuntu Studio would use everything on this sound card? [19:25] without missing anything? [20:11] I found this sound enhancer in Linux, just now -> http://soundpimp.com/guidelines/computer-audio-enhancer-linux/ [20:13] It is for system wide (OS) too. [21:54] Hi guys.
