DevTray Bug

Not too sure what's going on with it, but when I try to add it to the 
panel I get an error pop up "ExpatError: junk after document element: 
line 1, column 26"

Playing WAV files correctly

Hi,

I've been experimenting what some new USB sound interfaces that can handle
soundfiles at rates up to 96k samples/sec and with sample sizes of 24 as
well as 16 bit. However I'm having difficulty with finding a player app
that simply does this with no snags. (More about that below as context for
anyone interested!)

I've just tried downloading and using the ROX-app 'MusicBox-027'. However
this doesn't work at present. I have AlsaPlayer and Audacious working with
my alsa default device and they play things like 44.1k/16bit wave files
fine. But when I try the same wave files with MusicBox the display says
'Playing' for a few seconds, the time elapsed stays at zero, and it then
stops. No sound output. I have tried each of the alsa output options. No
sound.

Just giving files to MusicBox by drag and drop on my ROX filer/desktop. The
files don't have names that tell you 'artist' etc as many are simply LPCM
test tones or other test material. Not all 'songs', and no 'tags' in the
headers of the wave file. Just the basic 44-bytes for an LPCM wave.

Can anyone suggest what I may be doing wrong?

Context:

Trying out (currently) two devices:

1)  a Halide Bridge USB-SPDIF convertor. This will accept any normal rate
up to 96k and can handle 24 bit (in fact requires S24_3LE format which I've
specified in .asoundrc when making it the default).

Re: Playing WAV files correctly

I've had an off-list email about this asking for more info/details for the
list. So I can add the following.

Older USB 'sound devices' did tend to be limited to 48k/14bit. But the
newer 'asynchronous' USB devices *do* work up to 96k/24bit. 

They also do *not* require a specific driver to be installed. 

All you need to do to get 'aplay' playing up to 96k/24bit is to have the
appropriate details in your ALSA settings - e.g. in .asoundrc. IIRC the
next generation of devices may also reach 192k/24bit.

So the problem seems to be getting specific player apps to actually send
data to the default alsa device. AlsaPlayer does this, but refuses to play
anything above 48k. Audacious does this up to 96k, but only for 16bits even
when told to output 24 and avoid processing.

MusicBox - which is my main interest here - simply fails to play anything
even when I choose either of the 'also' options it offers. All I observe is
that it shows 'playing' for a few seconds with the elapsed time staying at
zero, then stops. The time it thinks it is 'playing' is far shorter than
the duration of the files. This happens even for 44.1k/16bit wave LPCM
files.

So the problem here is that MusicBox doesn't work on my system. Does
anyone recognise the syptoms or suggest how to 'fix' MusicBox?

Slainte,

Jim

ROX on Gobo

Is anyone using ROX-Filer and ROX-Session on Gobo Linux, at all? It
strikes me as a pleasing pairing and I'd like to try it out, but I
don't really know where to start...
