Cubox plays with click/pop sound 投稿者:wongcwwilson 投稿日:2013/03/24(Sun) 13:44 No.2465 home
Hello, I am a cubox user and install the cubox-audio "2012-12-22" image. While I play the music file which is 24/192, the song comes with repeated click/pop sound. However, it does not happen if the file is 16/44.1. I also change to cubox-audio "2013-03-13" image but still have click/pop sound.

For your information, I add a DDC in between the cubox and DAC becasue my DAC does not have USB interface. And the DDC used XMOS chip.

I wonder if it is because of the USB driver. May I know if I need to install a USB driver in cubox? If not, may I have your advice the cause of this problem and any recommended solution?

Thanks for your help, Wilson

Hi Wilson

About noise of cubox and DDC there is information in this thread(in Japanese). The conclusion is that some DDCs with xmos chips cause noise on cubox.
I am not sure the reason but maybe cubox usb hardware and driver cause noise. 2013-03-13 image is tuned-up to remove noise therefore if you have noise in this version, there remains a way to change ddc that can play with no noise on cubox.

Hi Mr Yo, thank you so much for your advice. I will try to change to another DDC. By the Way, I find the cubox with a HDMI output. Since my DAC has I2S input, can I connect them by a HDMI-I2S cable in order to bypass the DDC? Thanks again for your help. And heartfelt thanks for your cubox-audio image. Without your great thing, I don't think we can enjoy listening music in this way. Thanks, Wilson

Hi Wilson,
I guess the HDMI port in your DAC is an implementation of I2S LVDS on HDMI. In other words, it is not plain I2S but a differential mode of I2S which allows longer transmission distance.

While the HDMI port of Cubox is just a display port in circuit design point of view. I afraid it can't be changed to I2S LVDS simply by modifying the software part.

Alternatively, it is suggested that a DDC with I2S LVDS HDMI output is best suit your case:

I think you need a driver to handle HDMI input and I2S audio data. There is no driver for it, therefore it is impossible for now.

tks for all of your advice. By the way, may i know if it is possible to change the buffer setting in cubox? if so, would you mind show me how to write command in it because i am not an IT people. I have no IT background. I try search over internet but still dont understand the language of linux command. tks again.

Hi wang

What kind of buffer do you want to change.
Anyway you can change it by Nano(linux text editorlike notepad in windows). Nano can be called from command line like this.

nano /directory-Name...../conf-files-Name

For exsample if you want to change mpd.conf, please call Nano like this.

nano /etc/mpd.conf

Hi Mr Yo

Thanks for your valuable advice. Finally i fix my problem. its all because i connect it by nfs. if i change to cifs, no more click sound. and the sound quality is terrific. tks for producing such an amazing cubox image and your help all along. Have a happy Easter. Wilson
