I could hear also marginal sound differences between the versions out: in particular the first versions are to me with the best sound quality in recollection. Even if it may be an imagination, still I would post pursue with pleasure to it again. In the other forum I have asked for assistance regarding installation of the previous versions: note please, that I use now SBT only for internet radio (> 192 kbs) and do not own no server: Jacky's Profile: http://forums.slimdevices.com/member.php?userid=38257 View this thread: http://forums.slimdevices.com/showthread.php?t=94855 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Triode's USB 24/192 plug in - sound quality impressions
It has been reported elsewhere that tuning the kernel module parameter nrpacks may have an impact on sound quality with EDO when using a usb dac. This can be achieved by: echo NUMBER > /sys/module/snd_usb_audio/parameters/nrpacks Please note that if you try this tuning parameter there are two things to look out for: 1) The kernel we use will limit values of nrpacks to between 1 and 20 - any values larger than 20 will be silently treated as 20 2) This parameter is only read at the time the usb audio device is created. With EDO this occurs while the kernel is booting as we need to have the device available for the squeezeplay application. I'm not convinced at present that we can effectively change this parameter with EDO in operation. I'll produce a test kernel to check this.

It has been reported elsewhere that editting
/etc/squeezeplay/userpath/settings/SqueezeboxFab4.lua to alter buffer
tuning and output device parameters has an impact on sound quality. I
do not believe this to be true. The EDO applet is designed to run
before SqueezeboxFab4 applet and hence claims the output device. This
means that any audio related initalisation performed by SqueezeboxFab4
is ignored.
The relavent code is from squeezeplay/src/decode/decode.c - this returns
ignoring the settings if Decode: open() is called a second time.
Code:
static int decode_audio_open(lua_State *L) {
struct decode_audio_func *f = NULL;
if (decode_audio || decode_thread) {
/* already initialized */
lua_pushboolean(L, 1);
return 1;
}

Re: [SlimDevices: Audiophiles] Triode's USB 24/192 plug in - sound quality impressions
It has been reported elsewhere that sound quality of EDO 0.7 is not as good as EDO 0.6. I do not believe this to be true and wanted to confirm for users what the changes are between the two versions. There are two changes: 1) A new option on the buffer settings menu (no impact if you don't use it) 2) New code in jive_alsa which overrides the buffer setting in the case that resampling is involked. The change to the code is here: https://github.com/triode/squeezeplay/commit/198f7818c95261bf3fd14110df1004a4e7c35c9a In short I don't see a reason for people trying to install 0.6 rather than 0.7.
