I interested in "Line In" (capture) support. Do you really expect that someone has gone through all those soundcards, determined the chipsets and tested them with alsa? Buy it and try it. If they follow the usb specification for soundcards they should work. But that is a big if. Note that they might require the loading of firmware, and it may well be that Linux/alsa does not have the appropriate software to load that firmware onto the cards. So, buy them all, test them and let us know.

I hope you'll enjoy learning at your own expense. You are the one who asked, not me. I do not care if any of those usb sound chips work. You do. Now maybe if you told us what you need or want, we could give some useful advice. But giving us a list of 20 cheap chinese usb soundcard knockoffs and asking whether they work under linux is not likely to get you useful information. If you want a usb soundcard, I have used the Maudio Transit ( it used to be about $100) for many years, and have used to to record a published CD. It has very good distortion and noise behavior. If that is what you need or want, there is a suggestion (yes, it does work with Linux) And you still have not told us why you donot just use the onboard soundcard. > > --Sergei. -- William G.

By you telling us which you still refuse to do. So, again, why do you not tell us what you need and we may be able to make suggestions instead of asking us to rate a bunch of fly-by-night el-cheapo soundcards. Note if you need more than two inputs it would be a serious mistake to buy say 6 cheap usb soundcards to get 12 inputs. They will all run at different rates, and after a minute will all be out of sync with each other. If you want a 6 input or 12 input soundcard say so. |

I know how to deal with different sample rates and synchronization problems in the application I need such cards for. Since you don't know how I deal with synchronization problems, it's a serious mistake to tell I'm making a serious mistake. The only question I have is whether these cards are supported by ALSA, and so far you've been useless/distracting regarding the question I have. --Sergei. |

Fine, I have given you my advice. Whether anyone else wants to give you any advice is up to them. I certainly would not have done so had I realised what your attitude is but they can make up their own minds.

Ha! I understand that bear baiting was a popular sport in ancient Russia? You seem to have unrealistic expectations. If you want advice from the nice people on this list, you should be polite and ask nicely. The more information given, the easier it is to answer. I had originally written a response, but deleted it, but I'll summarize it again... Maybe YOU lack imagination? People are BUSY!!! No one has time for your "guessing games". This is "community project" software, freely made available, and developed and supported by volunteer efforts by interested (nice) people. You should not come in here making DEMANDS! The way it works in the "real world": you ask the companies that make the cheapie audio boards, and should be supporting their own products. You will probably find that your cheapie potential purchase is of absolutely no interest to them, and they will not even reply. After that you could ask forums (asking nicely works better). Finally, you can buy board(s) and try them out yourself, and share your observations (if you are a sharing kind of person? are you?). I'm hoping this was all a linguistic or cultural misunderstanding, and we can now "play nice". If I understand Bill correctly, he was willing to answer a specific question, in a couple of minutes in an email. He even offered to correspond to help determine the real question(s). You don't seem to want to help him help you. Too bad. Remember: PEOPLE ARE BUSY!!! You killed the bear. Happy now?

Hi Sergei Steshenko! On 2012.04.30 at 02:03:34 +0400, Sergei Steshenko wrote next: > > You apparently lack imagination. > > Here is a number of hints for you: > > 1) how can you know how many input channels I need ? > 3) how can you know whether my computer (which is not necessarily a desktop) at has "Line In" input ? Making lots of USB soundcards to work properly might be an issue by itself, even if each card works separately. There can be various issues with USB bus causing latency problems resulting in cracking and other problems if you actually try to use lots of USB soundcards. Reliable solutions for getting lots of line input on USB are using devices which are made for that; of course it won't be as cheap as a bunch of USB soundcards, but they are made for this job. There are various devices with these functions from M-Audio, E-MU and some other manufacturers. An example would be M-Audio Fast Track Ultra, USB 2.0 device which provides 8 analog inputs - I haven't checked if it works with ALSA, though, but I'm pretty sure it's possible to find something that works. That said, it's probably cheaper to buy lots of cheap USB single-channel soundcards from ebay or DX or something and check if they just work - and if they don't, think about real multichannel USB interfaces. But don't assume that they will all work together just because single one did - check if they actually work correctly when you feed required amount of input streams into them. -- Vladimir |
