First of, welcome to the forums and thanx for a most perfect bugreport!

You could try this patch as it lowers the alsabuffer, although I´m not sure this is whats causing your issues, if the patch in the ticket works it would be great if you could try the one I mention and see if that helps aswell.

thanks will try that tonight and see how it goes i see on that ticket u made a note saying that its better to add m_dwPacketSize = m_BufferSize / 10;
at line 236. is that still the case or?

[topfs2]

Hope it works for you.

Well my comment is more of a "If the first patch works for you please revert and try this aswell, if the works it would be better, if not then something else needs to be done"

Cheers,
Tobias

yeah same issue. here is my debug log http://pastebin.com/m1c8ba629

should i even try the second patch?

[topfs2]

Please do and say if it helped.
Cheers,
Tobias.

looks like the file has changed quite a bit in the new revisions and putting m_dwPacketSize = m_BufferSize / 10; @ line 236 gave an error during compile. anything else i should try?

[topfs2]

yeah it has changed quite alot, actually even fixing the issue explained in that ticket.

So make reallyclean and revert any files and do
configure && make && make install
and XBMC should work!

disclaimer: make reallyclean will clean ALL so save any userdata in the svn dir before doing it

Cheers,
Tobias

solved it seems to have been an issue with an improper modeline in my xorg.conf

removed the improper modeline and reconfigured with fglrx now everything is running smoothly
