I did an update today and I still have that same crackling problem with my sound. Even the login sound is crackling now. I hear some oscillating sound all the time, except when I do a Mute or disable the PCM source.
I read about the crackling sound problem also in thread http://ubuntuforums.org/showthread.php?t=843012. Is it probably advisable to update to ALSA 1.0.19 and Pulseaudio 0.9.15? I have also posted a further bug report 349228 which contains further information about my hardware: --------------------------------------------------------------------------------- I just did the ISO testing with the daily-live image (MD5 check-sum 03b63dada5e5fce0119a52d822e406a1). The audio test case hsi-001 didn't sound at all. Only when I went to Preferences->Sound->Test I heard a crackling sound fading into a clear tone. Stopping the test sound resulted again in a crackling. I have to mention that I didn't install anything additional to the standard ubuntu install (Jaunty Beta of today), I just checked the Internet and restored my Evolution-backup before I started with sound testing. My hardware is a Toshiba satellite M40, sound card is ATI-IXP with a Realtek chip ALC250 rev 2 (at least according to what alsamixer shows). Sound didn't work properly since Intrepid. I know there are already other reports about crackling sound. But I didn't find yet a hint/workaround really working reliably on my system. Can I help in finding the problem, what can I do next? Here is what I get with "aplay -l": **** List of PLAYBACK Hardware Devices **** card 0: IXP [ATI IXP], device 0: ATI IXP AC97 [ATI IXP AC97] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Modem [ATI IXP Modem], device 0: ATI IXP MC97 [ATI IXP MC97] Subdevices: 1/1 Subdevice #0: subdevice #0 In the attachement there is a screenshot of the sound preferences how they come after installing. After a reboot I heard the login sound properly, thus my hardware seems to be alright. Then I started Firefox and then repeated the sound test in "System->Preferences->Sound" and it still crackles. -- Sound went chopped, crackling and stottering after playing some streams https://bugs.launchpad.net/bugs/347588 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
