Hi all, I have some "progress" in mentioned issue. Issue is reproducible on quantal kernel (3.5.0) too. I attached quantal repo and installed kernel from it on my 12.04.
But the trick is that issue reproducible only after full power-off of freshly installed system (or even kernel, the magic is that issue dissappeared after I install 6.5 and reboot my system, but it appeared again after full power-off). Looks like it's regression for older systems. I found out forum's discussion related to 11.04>12.04 migration and troubles with ALC268. I have no chance to install older kernel from 11.04 because it has poor support for particular Broadcom WiFi device. Could anyone please take a look at this issue? This is my last chance to keep Ubuntu on my friend's laptop. He is going to install Windows 7. Thank you in advance. PS Actually, I've dived into kernel git and found out that maintainer has reworked all patch_realtek.c code according to new approach (or facility in snd-hda) called "auto-parsing". He deleted all hard-coded control elements and parameters from patch_realek.c. Feel free to ask me for additional dump/logs or something else. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1032851 Title: [Satellite A215, Realtek ALC268, Speaker, Internal] Underruns, dropouts or crackling sound To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1032851/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
