Please note that this solution is much more involved; the driver, library, and pulseaudio all need to be aware of this information.

[Bug 204898] Re: Better (non-linear) volume control
Try my new ppa (ubuntu4~ppa1): https://launchpad.net/~xt- knight/+archive/ppa Plus, set Master to 100% and adjust PCM. This is a better method, because Master goes from 0-31 and PCM goes from 0-255, at least on most cards. PCM is a higher resolution adjustment. It works with PulseAudio in my experience. I think PulseAudio adjusts through ALSA anyway. This is why I made the change at such a low level. The constant is now 0.5 instead of 0.7. Don't use PulseAudio's volume control in pavucontrol. I think there's other serious bugs in that right now, at least in Karmic. Use alsamixer under the terminal and set Master to 100%, adjust PCM. Sometimes you have to press the down or up arrow multiple times simply because all the volumes you adjusted to map to the same volume. Or maybe it's a rounding issue. dB gain readings may be broken with this patch. It should be able to be fixed easily. ** Attachment added: "vol_ctrl_0.5.png" http://launchpadlibrarian.net/29779611/vol_ctrl_0.5.png -- Better (non-linear) volume control https://bugs.launchpad.net/bugs/204898 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

Hey Mario, I'm not sure, but Karmic packages on Jaunty should work. Anyway, I took measurements with a sound meter and my headphones. I think we're just migrating the problem. Alsa is already a dB scale. This patch maybe makes it more linear to the ears. I don't know enough about sound to say for sure. It works, but needs some tuning or a more advanced algorithm.

I tried alsamixer, both channels (main, pcm), but with pulseaudio running.. maybe if i quit pulseaudio, it would work.

[Bug 204898] Re: Better (non-linear) volume control
Hey Mario, Have you tried with alsamixer? I did try making it 0.2 (instead of 0.7) actually earlier on but this seems to move the problem to the bottom end of the volume control. I'm not sure if what I'm doing is the correct way to do it but there is a difference with alsa mixer. I seem to have more luck with the Master channel than the PCM one but a short check inside the code told me the PCM one was working. I haven't been able to confirm anything though and I'll continue doing some testing. -- Better (non-linear) volume control https://bugs.launchpad.net/bugs/204898 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

Thanks for the patch xtknight.. but i can't hear any difference. Maybe it's cause of pulseaudio, I'm not sure. Could you try to make it more curved? So the difference would be more obvious.

[Bug 204898] Re: Better (non-linear) volume control
Here's a debdiff for karmic that enables *EXTREMELY EXPERIMENTAL* support for a logarithmic volume control. I warned you there. Honestly it was pretty easy (so easy it's deceptive) but I don't know if it works perfectly. I haven't been able to try it on a card with a negative volume lower bound. e.g., in 'amixer -c 0' (for card 0), you'll see this: Limits: Playback 0 - 39 My code supports a negative lower bound (less than 0), but I don't know if that ever happens. Consider this a proof of concept. It should be tested a lot more until it's in the code base. I attached a graph of how it works. The straight line y=x is how alsa is now. The other plot is how alsa will respond with the logarithmic scale with setting 0.7. More sensitivity on the upper end. Debdiff and ppa will come in a second. ** Attachment added: "logarithmic volume graph" http://launchpadlibrarian.net/29768808/log_vol.png -- Better (non-linear) volume control https://bugs.launchpad.net/bugs/204898 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

Having linear volume control is not only frustrating but also, frankly, embarrassing. It really shows that the developers working on the audio system don't actually understand audio that well. I know that's a fairly strong statement to make, but I stand by it. Logarithmic volume attenuation is electrical engineering 101 type stuff, really basic & fundamental.
