Hello Juanito, Rich, Curaga,

i repeated the whole set of checks on my MacMini (unable to boot from stick, so must use CD)
To have a comparison I added a tc 6.4.1 frugal installation named to tce641/ with alsa.tcz and so on, and it works and sounds fine. And yes, I've seen the versions difference of alsa versions!

Looking into the info to alsa I found that Xorg-7.7.tce and Xorg07.7-3d.tce were missing, so I added them.
Did not help to sound.

Looking into the info to alsa-config.tcz I found that it should have  alsa-lib-1.1.0.tcz  and  alsa-utils-1.1.0.tcz  but did not find either of them when looking into  AppsBrowser - Apps - Maintenance - Md5 Check.

Can this be the problem? Sorry I'm not a coder :-/

Chattrhand....   :o

With each Alsa revision I typically see many improvements, these can cause some challenges.   While it appears most systems are supported with ease, with an increasingly greater range of Audio hardware there often requires a few extra configuration steps regardless of whether the hardware worked OOB on previous Alsa releases.  It's unfortunately the nature of the beast.

Additionally, it appears that some basic troubleshooting steps or methodology have been missed in your efforts.

An experienced TC user would know that to boot a USB installed TC on a Mac you would need to install an EFI compatible Boot Manager such as grub2-efi from grub2-efi.tcz.   However by default a CD will boot (blame Apple for that).

reading the posts here I'm not at all sure if you're aware that TC needs to be instructed to use a specific tce directory, when there are various older installations (additional USB's, HDD's and even a bootable CD left accidentally in a CD/DVD tray) to choose from.  Otherwise there is no guarantee the desired tce or cde directory is actually being used.  This can and has been the cause of considerable confusion for many (usually new users).    It's best therefore when creating a USB bootable TC to clearly identify within the boot config file which USB and TCE directory to use using Labels, UUID codes, etc etc..


Honestly if you remove the possibility of tce directory install confusion, I believe at worse case an Alsa config file is all that is required to bias Alsa to use specific hardware.    Actually this is how I accomplish this task for obscure or new audio hardware.  Alternatively use pavucontrol with pulseaudio to switch the audio source and output.

basic steps:
1. make absolutely sure there is only one installation of TC installed (be that a CD, a USB or HDD)
2. load only alsa.tcz
3. run alsamixer to
  a. select correct hardware and
  b. unmute require controls
4. if still having issues begin the typical alsa troubleshooting

good luck

I'm puzzled that sound does not work on any of your machines (MacMini, iMac, Acer tmp 453, Lenovo b40-30).

Unless of all the machines have the same hardware, this would seem to indicate that it is not a kernel driver regression, nor that hdmi is the default and you're trying to listen to analogue.

Did you examine dmesg on the same machine with tc-6.4.1 and tc-7.1 as curaga suggested?

Note that, although they might not have the same hardware, sound works on my mac mini.

Hi, I could give you a report from alfsa-info.sh, this has about 28000 MByte.
I have auto-uploaded it as required  to www.alsa-project.org  and hope the maintainer can help.


By the way: with tc 7.1 the touchpad is no longer working after installation of both firefox-esr or firefox-getLatest. Haply I can use a usb mouse...

chattrhand, I'm fairly sure your issues are related to a lack of configuration.   This troubleshooting link helped me figure out how to configure my Alsa installations,  hopefully it will also help resolve your Alsa issues.
