Overdriven sound in jukebox mode? [Resolved]

[jol]

Hello,
I installed Subsonic yesterday and I am pretty impressed by the great combination of server and Android app. Music playing on Android is fine, including artwork and searching the server - thanks for all the good work. However I am struggling with jukebox mode, where the signal appears to be overdriven or distorted in all "remote volume" control setting except the lowest setting (after silence). As I am using a cheap USB Sound card (mere presence was required for software I used earlier) it may of course be a hardware issue as well, any experience with other sound cards appreciated.

Problem Description: overdriven/distorted sound in jukebox mode
Troubleshooting Steps: tried various settings in volume controls of Windows and in Android app
Playback Application and version: Subsonic for Android 3.3
Subsonic Version: 4.6 (build 2583) – December 6, 2011
Server Version: jetty-6.1.x, java 1.6.0_27, Windows Server 2008 R2 (86.5 MB / 96.7 MB) -
Hardware Platform: Windows Homeserver 2011

Problem Filename: no specific file, tried several

Any help or advice what to try appreciated.
Thanks, jol

I don't really use jukebox mode, but I did try it out for a bit, and the sound wasn't overdriven. Check all other places from which you can control the volume. Maybe it's a problem somewhere else down the line.

I am not sure about WHS 2011 but on WHS R1 you need to remote login using mstsc /admin to access the audio properties.
If it's a USB device it will probably be using C-Media chip so make sure that WHS is accessing the correct drivers

eliminated external amplifier, but same result with headset. I am not aware of more places in Windows. Does subsonic have its own mechanisms?

I am not sure about WHS 2011 but on WHS R1 you need to remote login using mstsc /admin to access the audio properties.

no matter how one connects with RDP, audio is screwed up afterwards. But I did my tests directly logging on to the console before using RDP at all (my WHS has keyboard, mouse, and monitor attached).

If it's a USB device it will probably be using C-Media chip so make sure that WHS is accessing the correct drivers
.
.

how can I figure out the USB soundcard is using that chip or wrong driver? when I look at the device properties I get the following:
Hardware IDs:
USB\VID_1130&PID_F211&REV_0204&MI_00
USB\VID_1130&PID_F211&MI_00
compatbile IDs
USB\Class_01&SubClass_01&Prot_00
USB\Class_01&SubClass_01
USB\Class_01
and if I figure out the server is using the wrong driver, where can I obtain a better one? Any pointer?
Thanks, jol

As you do not have a headless server it becomes easier to debug
Does it distort if playing back via WMP (hence rule out Subsonic config)
If it does then transfer the USB to another pc & retest.
If it still distorts then go Amazon and buy another one
If not then its the driver on the WHS pc - is it a generic Windows driver or did it come with the device?

it turns out sound is distorted with that USB adapter using WMP and also on a different Win 7 computer. I will shop for a different sound card.
Why did I not see these options on my own?
Thanks for the help, jol

I have a really nice USB audio interface and it works just fine on everything but Jukebox Mode in Subsonic. I did a lot of digging and have figured out that the volume control on Jukebox mode is actually controlling the MASTER_GAIN on an input rather then just a Volume on the PC's mixer. I have rewritten some areas of jukebox\AudioPlayer.java to instead set all mixing devices with speaker ports to volume 0.0f -> 1.0f. This means that your application volume slider in your operating system mixer should be moving in unison with the one on your Phone App or PC Mixer.

This has not been tested on OSX or Linux. I think it should work though.

If anyone is wanting to look/try/whatever the modified Jukebox AudioPlayer.java I will upload it here. Use the below instructions to get it running:

1) Prep for Building using this Link: https://sourceforge.net/apps/mediawiki/subsonic/index.php?title=Installing_Starting_And_Stopping_Subsonic#Building_from_source
2) Replace Drive:\Extracted-Source\subsonic-main\src\main\java\net\sourceforge\subsonic\service\jukebox\AudioPlayer.java with the one attached
3) Build
4) Place subsonic.war into your Drive:\Program Files\Subsonic Folder

I too have been experiencing an issue with Jukebox mode and distortion, but with Linux. I am running Subsonic on a Raspberry Pi under the latest Rasbian. For those in the know, aplay, mpg123, shairport and so on (i.e. everything I've tested) all play back the same file at the same audible volume and there is no distortion. I have a C-Media USB sound card and it's working very nicely, thank you very much, other than for jukebox.

As all other software plays back fine with the USB card's mixer set at 0db (100%) and no other mixers in the chain, I suspected that something in Subsonic must be causing a positive gain, causing clipping of the audio data before it gets as far as the USB sound card and, possibly, before it gets to ALSA (not sure yet). I.e. Subsonic is setting a gain outside of the range -inf to 0db. This may be desired behaviour for some people if they want to boost quiet tracks, but this isn't the best solution for those that want to set a max volume on their amp/speakers and then be able to fling the Subsonic volume slider up to max without fear of being deafened / distortion.

That all led me to your post and it all makes sense.

I haven't tested your changes on Raspbian yet, but I will when I get time. I'm not sure if there are "application volume sliders" like there are in Windows, but given it's all just Java, perhaps there is an equivalent under the covers than I'm not aware of - I'm pretty new to audio on Linux, although I've been Java-ing on Windows for years and Linux-ing in server environments too.

I just wanted to let anyone tracking this thread know - I'm going to work on this and see if there's a solution that works on Windows and Linux.

A question for you though Bryan: Which release did you base your changes on? I downloaded the source for 4.8 and the comments show:

Code: Select all

@version $Id: AudioPlayer.java 2493 2011-10-31 21:20:13Z sindre_mehus $

...same as your source file. However, there are other changes that seem to be unrelated to your fix. I wonder if this file changed between versions and the version number in the file didn't update.

Thanks.

UPDATE:

Well, I've resolved the issue of distortion at higher volumes. I will post a new topic covering what I did in the hints/tips sections when I get time.

The short version is that Subsonic was reading the min/max gain values allowed by my sound card and applying them across the range of the slider using its (very strange) gain function. My sound card reported a gain value range of -88dB to +6.63dB. Note that this resulted in a gain increase when the slider was above about four fifths of the way up. With tracks with typical modern 'loud' mastering, this resulted in clipping.

I modified the Subsonic jukebox source code to use a much more sensible gain function when going from the linear slider value to actual gain (reduction). I used the same formula as used in the Shairport code, which itself is based on the Airplay standard and roughly maps the slider full range from -30dB to 0dB gain, with a zero-value on the slider setting the gain to the minimum value allowed by the sound card - i.e. damn near silence.
