Hi Lorien and all

I want to report on the outcome of this issue. This may have a bearing in the on going discussion.
The problem is traced to the operating system that is based on ubuntu 12.04 and i think there is driver conflict. I also experience the fact the LIVECD testing works well but the installed version do not.
I replace the ubuntu 12 derivative with a an older version , I installed the Linux mint 10 and has great sound and is stable over the last 2 days. No tweaking of command line needed.It works right after installation.
Audacious sound the best in linux mint.

cheers and want to thank Lorien for the helpful suggestions.

regards

I have been enjoying the wave io for the past few monts and suddenly there is no sound last night.
The linux and window 7 OS both detected the LUCKIT usb audio device but no sound . I use the isolated output of the wave io to test on 2 dac that worked well before.

I am planning to test with the non isolated output.
I have a few questions

Any suggestions in troubleshooting and identify the cause of the failure?
The centre pin of the uFL is the live one ?
There is only one ground point in the dac i2s input and can i use the ground off any uFL socket ?
thanks for the help

BTW, Reo
i notice you use solid state drive. Any sound advantages when compared with spinning HDD?

hi KP
have not had a chance to listen to it on this mint 13 version , but if i install the 10 version i will report back on this , and will try audacious instead of VLC or compare., and to also see if the SSD makes a difference., i doubt the SSD makes a difference in music, as long as there is enough memory banks in your pc that is where the music is processed before you get to listen to it . the more memory you have the more the (RAM) Random Access Memory) will store the information from the bits in the music are stored and ready for play., it's other factors that come in to play when comparing music sounds.,that's a whole different field.

By the way KP The Ufl cable is a + and ground cable . The + is the center pin and the housing is the ground . I presume you are using WaveI\o so this point is important if using the + and ground from Ufl cable from the master socket of the WaveI/O to reach out to the BuffaloII The R17 pin has a + and a return ground which will go to directly back to the housing of the Ufl of the master cable . That is just the connection schematic of how it is done , there is more info naturally...depends how you have your setup.

By the way if i'm using SSD it the future in storage facility, no more hard drive heating up , it's like a huge usb drive the write and read is proportionned to the quality of the components and chips installed on the SSD which makes it go real fast in comparisson to a HDD., either way i will report back if i install Mint 10 or wait for the Minters geeks to upgrade their missing information that the Mint 10 has .

Just a quick check, in alsamixer you should get two vertical bars on screen. On the bottom of each bar, mine has an M 'mute' or '8' on its side the infinity sign, to unmute if mute shown, use the arrows and I believe the 'm' key, depends on the linux you are using, google mpdPup and it's in that thread, the store line may also work but no guarantees.
If you can see the M for sure it's muted, if it's locking I reckon this is where it's at, worth trying. To check on another Linux version, I can recommend mpdPup as wizards have been created to make install really simple.
Hope it goes well!

Drew.

Not seeing any M in this version of Linux so for sure it's on another version. I will look to alternatives as time goes on
tks for your input it's been helpful in diagnosing ..

In the next weeks will be complete my DAC modules to integrate to this XMOS USB-I2S module.

USB DAC 2 - Hi-Resolution System

USB 3.0 compatibility
 
to lorien and everyone

does the board currently supports and detects usb 3.0 structure ? If do so will it automatically downstream to usb 2.0 speed ?

Lorien 5th August 2012 07:24 AM

It was successfully tested on a desktop PC using NEC(now Renesas) USB 3.0 host controller. Didn't had the required amount of time to collect details but I've noticed that there's no difference between USB 3.0 and USB 2.0 ports on my motherboard. Also, I do not expect for WaveIO to work at USB 3.0 speeds because it simply can't :)
Kind regards,
L

So technically it won't work with usb 3.0 but from your short period of time testing it, it works...?

Lorien 5th August 2012 09:44 AM

Sorry if I wasn't so clearly! I've test it from curiosity... just to see if it's compatible with USB 3.0 ports (in my case based on Renesas controller): and it is! I've played few tracks for about 2-3 hours and after I saw (hear) that it's working properly I went back to assembly other WaveIOs. Time is not always on my side :)
Kind regards,
L

Thanks Lorien for clarifying that. IMHO the board works well with usb 3.0 although without taking the full advantage of the new data speed just like any usb 1.1 devices that still supports ver. 2.0 and works well minus the new data speeds advantage.
