11.04 "Boston acoustics digital speakers" intermittent sound

Does sound work in other applications?

Can you also give the output of:

lsb_release -a

Thanks

Does sound work in other applications??

sometimes I can get the speaker test to work but usually not. just tried to play a wav file no go, spits out errors such as "pa_stream_writable_size() failed: Connection terminated" i have the boston acoustics digital speakers that require the sound blaster live card. i had this problem last year when I first loaded 10.10 but it is fixable I just don't remember what was done.r I'll write it down this time I promise!I I remember it had to do with the alsa mixer there was a digital out switch i had to toggle but it doesn't seem to be working this time

Ok here it is, I toggled the SAME "analog digital out that I've messed with about 20-30 times today on my alsa mixer and wala! great sound started coming out. please help me figure out how to make these changes stick. I've seen that toggle toggle itself back earlier today(when it wasn't having any effect! ) I'd love to understand what is going on. so far I'm not having a lot of confidence in 11.04
thanks

still can't play certain music files tried ti=o play a cda file and got this error "Could not display "/home/william/Music/wake up/Track01.cda"." and earlier today the audio icon would change to a speaker with dashed lines instead of sound waves

sound is out again. and I didn't change anything. and now the analog out toggle isn't making any difference

Pulseaudio is used as standard. Install pavucontrol and test settings. Another GUI would be gnome-alsamixer.
Make sure the settings are consistent with gstreamer-properties.

Learn about codecs. Maybe there're some packages missing which need to be installed.

> play a cda file

There is no .cda file, rather convert to something else.

Problem solved!!!!!

I'll try to keep this short. I've had lots of trouble in the past with my Boston acoustics acoustics DIGITAL speakers and making them work right. I still think the problem was in the software, getting my soundblaster card to work right with the system. last night i decided to see it I could just try to rewire my speakers for analog. I did some research and behold! BA had an option on the circuit board for an analog imput! so I found the right analog jack, added the apropriate two resistors and two capacitors, and was done. I plugged it into my sound blaster card analog jack, same problem. intermittent sound. switched the plug to the onboard sound. and behold, no more problems! and it sounds just as good as the digital option. i'vs also removed the offending sound card. so the problem was either a bad sound card or a software mismatch problem between the onboard sound and the sound card. I'm thinking the latter. since the problem seemed to show up after an upgrade(including windows)

here's a link to the page that showes how to do the conversion

And P.S. the soldering of the resisters and caps(regaurdless wether you use standard or surface mount)is a bitch! but doable. the jack is easy, it uses "through holes" and the soldering is done on the back.

who ever moderates this, please link this to "Boston acoustics digital speakers" thanks to all those that have helped, and I hopr this helpes others!
