LinHES Forums :: View topic - Audio h-h-h-h-hangs when exiting recordings

The solution above posted by CIMLinux works fine here on my
ASUS A7N8X Deluxe.

However I get skipping sound when minimizing/maximizing windows
under KDE while playing back (other heavy PCI activity will probably
have the same result - I still have a PCI graphics card in my
machine).

Increase the value "buffer_size" to remedy this, like here:

slave {
pcm "hw:0,1"
period_time 0
period_size 1024
buffer_size 32768
rate 48000
}

(This goes in the section where the dmix plugin is used.)
Lower buffer_sizes will probably work as well. The changed rate
setting doesn't seem to be necessary, as ALSA seems to convert
on-the-fly into 48000 Hz anyway with the SP/DIF output, but I've
still changed it just for clarity.

I am using R5A16. I originally installed using R4V5 and this was not a problem. I have searched the forums and google and the forums with google looking for a solution to this problem and have not found one, so I am hoping someone can help. When I exit from recorded shows, the audio hangs up for several seconds on the last couple of sounds played, resulting in an annoying repeating noise. It goes away and returns to the frontend. When I play videos (AVIs, not ripped DVDs) this does not happen. It does happen with MP3s. Everything works, but I can not figure out what I changed between the old version (R4V5) and the newer version to make this happen. I did try some of the alsamixer tips in the documentation to no avail, and everything I have seen regarding the audio problems does not seem to apply to the PVR250. Perhaps an upgrade to R5A26 would be in order, but that seems like throwing out the baby with the bath. Any advice would be appreciated.

I found this page from the Alsa mailing list: http://www.alsa-project.org/alsa-doc/do ... s-full.php I think the change this person is referring to changes made to his ~/.asoundrc file: Quote: The solution above posted by CIMLinux works fine here on my ASUS A7N8X Deluxe.

Hope this helps.

I don't have this configuration file (under mythtv user?). Any pointers as to where it might reside? I searched the whole system and did not find it. I re-ran alsaconf to reset everything to defaults, and this clears the problem for a period of time. It eventually comes back though. As if there is some sort of buffer that fills up gradually. Sorry for my ignorance here, I am just a hack when it comes to this stuff.

The hang comes back within a day or so of watching / recording stuff.
