ALSA update to 1.0.27
« on: July 28, 2013, 12:21:49 AM »
Hi bmarcus

I noticed that ALSA has been updated to version 1.0.27 (whereas the current version in microcore is 1.0.26). There are some fixes in the PCM handling which might be related to a problem that I have with getting 192 kHz audio out via the HDMI.

So do you have the time to update the ALSA package, or can you briefly outline what has to be done, then I could give it a try.

PS: thanks to you guidance I'm now able to build new kernels and modules for the piCore - currently I'm using version 3.9.10+. (with ALSA and wifi modules updated accordingly)
If you are you interested in these, then I could send them to you.

I will update ALSA in the next days hopefully.

Is your 3.9 kernel is a stock kernel or a Raspberry Pi variant?

Thank you for that   -  if you have the time to briefly describe how you do I would really like to see/know how you work you through such an update of the ALSA.

The kernel and kernel-specific ALSA and WiFi modules are derived fromthe kernel obtained here: https://github.com/raspberrypi/linux   (now it actually is 3.9.11+)

Nothing special. As in most cases, there are build scripts where only the version number must be edited, everything else done by the script except .info file update.

Build scripts are available in the repo, see .../tcz/src

hi bmarcus.

Thank you for the updated version.

Yes I see some differences. I think that the problems I had with outputting 192/24 audio through the HDMI are improved (actually it is now working very good)
However, I also had some problems with the new version. I think that the Dmix option now wanted to resample most of my 44100 files to 48000 kHz, so I had to disable this option.

Other changes are that You also included the alsamixer and ncurses in this build.

one of the changes that a resampling plugin is added. Probably what you see is a side effect of the plugin.

Mixer GUI is using ncurses, it is why ncurses added as a dep for convenience, however in any other cases it is not needed.
