[Bug 234165] Re: Hardy: sound level low, poor quality on Macbook Pro
I can confirm this bug for Ubuntu 9.04 Alpha 5 64-Bit with all updates as of today. There have been issues with Ubuntu and this MacBook Pro rev. 3 here in the past (eg one day after some update I couldn't get any sound any more at all), and sound quality has been low and max volume has been too low in the past. But now when I start the new 9.04 system the sound is even far worse than with 8.10. It's like rough and slightly crackling. No good at all. Seems to me sound has been far better when I booted up the system for the first time. I haven't done any substantial changes on the system since then except for installing the proprietary Nvidia-180 driver (I would have tried the Nouveau open source driver but the installation routine did not offer to do so.) ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- Hardy: sound level low, poor quality on Macbook Pro https://bugs.launchpad.net/bugs/234165 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It seems to me that the issue with low level and poor sound quality is because the third speaker of MacBooks aren't used.

Many of your audio issues should be addressed in upstream alsa-kernel git.

I have just noticed (simply didn't need this before) that the microphone is muted. I have played with alsamixer, kmix, artscontrol, krec, audacity - absolutely no sound input. I don't know how to debug this problem, everything in the interface of the applications tried suggests that the input channels are there and they are not muted. -- Hardy: sound level low, poor quality on Macbook Pro https://bugs.launchpad.net/bugs/234165 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The report above is wrong, it seems, the output of alsa-info.sh shows Driver version: 1.0.16 Library version:1.0.17rc2 Utilities version: 1.0.17rc2 Modules install seemed to go OK though, is there something similar to /etc/default/linux-restricted-modules-common for alsa? ** Attachment added: alsa-info.txt http://launchpadlibrarian.net/15445582/alsa-info.txt -- Hardy: sound level low, poor quality on Macbook Pro https://bugs.launchpad.net/bugs/234165 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
