I just made an upgrade to my system. I am currently running 2.6.32-19-generic and the bug persists. Like I said in comment #13, the necessary patches do not exist in 2.6.32. ** Tags removed: needs-kernel-logs needs-upstream-testing -- [karmic] CX20549 100% volume means 35dB (distorted output) https://bugs.launchpad.net/bugs/461521 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

Hello, The necessary patch to fix this issue [1] is not present in Linux 2.6.32 [2]. Also, I updated to the development version of Lucid two weeks ago and the issue was not fixed. If you want, I could retest this on Friday.

Hi Cristian, This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 461521 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.] ** Tags added: kernel-sound ** Tags added: needs-kernel-logs ** Tags added: needs-upstream-testing ** Tags added: kj-triage ** Changed in: linux (Ubuntu) Status: New = Incomplete -- [karmic] CX20549 100% volume means 35dB (distorted output) https://bugs.launchpad.net/bugs/461521 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 really makes sound, but a disaster, the sound is harsh ,and sometimes when i am not playing any music, it produces 'music' (i guess it's electric current) , boo~boo~pang~ -- [karmic] CX20549 100% volume means 35dB (distorted output) https://bugs.launchpad.net/bugs/461521 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

Could you please type: cat /proc/asound/card0/codec#0 | head and paste the output here, to see whether you have the same codec as I have.

I don't know whose fault this is. The kernel correctly exposes the fact that the sound card might distort. Shouldn't it be pulseaudio's job to limit the maximum volume? ** Package changed: alsa-driver (Ubuntu) = linux (Ubuntu) -- [karmic] CX20549 100% volume means 35dB (distorted output) https://bugs.launchpad.net/bugs/461521 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
Re: [Bug 461521] Re: [karmic] CX20549 100% volume means 35dB (distorted output)
No, it is *not* PulseAudio's job to maintain a list of known-good (or known-bad) cards. It's the sound driver's job to correctly expose dB info, which clearly is not happening for your codec and controller. Again, Conexant is notorious for this, but it can be worked around in the driver. On Oct 27, 2009 8:10 AM, Cristian KLEIN cristikl...@gmail.com wrote: I don't know whose fault this is.

[Bug 461521] Re: [karmic] CX20549 100% volume means 35dB (distorted output)
Hi, If you think the problem should be solved in the linux package, then the following patch solves it for me. It is against the source from linux- backports-modules-2.6.31_2.6.31-14.16. Notes: - With passive headphones, at maximum volume, music is close to the pain threshold, without distorting. Then again, I'm not a loud music listener, so other people might want higher volume, especially if their music files are low-volume. - This radically changes the behaviour of pulseaudio and basically only the Master volume is used. PCM volume stays at maximum and only descends when the music is already very low (for me inaudible). Should I report this upstream? ** Attachment added: Patch to limit the maximum PCM volume http://launchpadlibrarian.net/34493089/patch_conexant.c.diff -- [karmic] CX20549 100% volume means 35dB (distorted output) https://bugs.launchpad.net/bugs/461521 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
