What is USB sound standard on Mac or Linux, that drivers no needed? Working new FW as DAC on Windows without drivers?

For lyrics in Rockbox on DX90 I used lrcplayer plugin. It worked OK with timemarked .lrc files, also worked with unmarked .txt files. Lyrics in tag I not tested. Manual say, that in lrcplayer working with id3v2 SYLT or USLT tags in mp3 files (only for mp3, no other sound files).

I see now on O2 schema, it is realy closer to my amp. In O2 are output resistors only 1ohm.

Hi Why is on this card dual opamp for IV covnersion? Or first channel is IV and second channel is filter?

Here is really schema of this amp: http://www.imagehosting.cz/?v=e10headamp.jpg Opamps was not biased, biasing is my modification. I make simulation - with 47ohm output resistors is output impedance about 12,5ohm. Now is output impedance 2,9ohm.

What You mean bad idea? Going with resistors below 10ohm? My headphones are Triple.fi 10 (32ohm) and SRH-840 (44ohm). With 47ohm resistors was sound little muddy and highs was not bright. With 10ohm resistors sound excellent. Very clear, punchy bass, bright highs with overal more energy...

Hi I have portable headphone amplifier based on this scheme: http://www.eleccircuit.com/wp-content/uploads/2011/05/increase-output-current-of-the-op-amp-ic-in-85mA-size.jpg only my is: Master - OPA128SM 4x Slave - OPA627AU biased 5mA to Class A over resistors How much are minimal safe and...

Have someone experience with bias to class A on OPA128SM? How much is best or maximal value for this opamp? I have good result with bias on OPA627, but OPA128 have only 10mA Current Output (OPA627 have 45mA).

Hi, we very please for Lurker L2 with dual boot. Rockbox is fast final and iBasso will not release new FW until several months. From I made RedBox, I never use Mango, bun now I must use it for DAC.   PS: Only one think miss in Your RockBox - Zoom in image viewer. On simulator zoom function...

  Make You Factory reset in Mango after update to 2.1.5? I (any others) had problem with playing files in Mango until I make Factory reset. From update I had very little time to listen, so I can not say, if here is any problems in Rockbox. PS: I am very happy for using RedBox :) For...

To headwhacker: New DX90 firmware is out and are good reaction on it. Please, can You make new FW with dual boot for Rockbox? Or You want wait on Lurker mod 2.1.5?

Yesterday I try everything (install new, unistall, reinstall), but I have a LOT of BSODs or not see ibasso in sound. Today I start PC, uninstall drivers, install new, connect DX90 and over 2 hours of listening all working. It sound better than my X-FI Prelude with OPA637. Yes, it have sound...

In my Theme is fast touchscreen switching between Playing screen, Database (Browser), Playlist, Menu, etc. In Playing Screen: - Press on Album Art = Database/Browser - Press on Song information = Playlist - Press on top of screen = Menu - Long_Press on top of screen = Shortcuts (this can be...

Thank, this function: type: file data: /mnt/sdcard/apps/app_rockbox/rockbox/rocks/apps/lrcplayer.rock   Not function: data: /.rockbox/rocks/apps/lrcplayer.rock But for theme this function: data: /.rockbox/themes/Redbox.cfg (real path to this theme is...

When I make shortcut to any plugin, I every receive Can´t open /.rockbox/rocks/apps/lrcplayer.rock . Shortcuts to .cfg files function. In rockbox simulator I can use shortcuts to plugins.
