Pithos loads stations, but won't play

[Dean Sellis]

I've installed Pithos (latest 0.3.9 release) and my stations load, the buffering message displays and goes to 100%, then nothing happens. It won't play any music. This is on Ubuntu 11.04 and everything is up to date. Here's output from the verbose command line:

No matter what I click on no music will ever play.

This just started happening for me recently as well. Pithos was working for a while. This is a Kubuntu 11.04 machine with KDE 4.7.00. PulseAudio, of course. My pithos -v output is similar to the original reporters.

I don't know if this helps, but if I strace the process, after it starts loads, and buffers, it generates this approximately once per second:

If you want the full strace output, let me know.

Addition details...somewhat fuzzy.

Today, I had an unrelated problem and ended up killing the pulse audio daemon. (Mind, I've restarted this laptop a few times). This evening, I started Pithos, and it started playing fine. Weeeeeeird.

I'll keep an eye on this.

[Adam Porter (alphapapa)]

Any updates on this? It works for me.

[Joshua Kugler (jkugler)]

No updates from me. Haven't been able to reproduce the problem since. I'm guessing it's some esoteric sound system glitch.

[Adam Porter (alphapapa)]

I'm guessing you're right. I'm marking it as incomplete.

I am currently having this issue, on Ubuntu 11.10 x64

bandaid to the problem, under Settings -> Advanced Settings -> Audio Format dropdown it was on mp3-hifi 3rd in the list. i set it to mp3 2nd in the list, and everything works as advertised.

I don't know if it's directly related or not because I don't get any clr error messages. I have JUST installed Pithos, & am running this version: Pithos 0.3.17. I first installed it from the Synaptic Package Manager, then, when it wasn't working, I ck the Pithos webpage & I found this bit of code to install/update on Ubuntu:

sudo add-apt-repository ppa:kevin-mehall/pithos-daily
sudo apt-get update
sudo apt-get install pithos

I use my son's Pandora acct since I'm living in his house (funny, huh?) but all I get when I start up the app is this:

Error: Gstreamer error: state change failed and some element failed to post a proper error message with the reason for the failure.

Someone above suggested they changed their preferred audio format from mp3 hi-fi to mp3 (3rd choice to 2nd) but I've tried all of them & none of them worked.

Also, don't know how to get the output gotten by Dean Sellis with "verbose" (don't even know what that is) or J Kugler's "strace" (this one either).

I'm running Lubuntu 11.10, all updates current.

If "killing the pulse audio daemon" will fix the prob, I'm all for killing. How would I get to the particular line in the source code? I'm thinking some notepad app but not sure how or where to start looking for it.

Any help for this grandma would be repaid in Karma. Thanks!

[Jessie (iluminameluna)]

Additionally:

The Stations load, I get to pick one, the songs start to load, the buffers go to 100% then the above message appears. & it tries another song & it stops "trying" at the fourth song at which point it does NOT buffer to 100% but says instead: Error: Resource Not Found.

If I go to the Pandora website, I can log in & play Pandora but I'd rather not have my browser open all night 'cause it just heats up my Asus Eee PC 901 even though the battery has been removed since I have it on A/C power. Plus I'm basically bedridden so I have it playing almost 24-7 & my comp gets awfully hot.

Thanks again ... =D
