   Hello everyone.
   Speaking of LinuxFromScratch, my best wishes for the enterprise of Filou and Shann, and while waiting for an official distro I turn to the experts for advice: I built based on the guide LFS-BOOK-10.0 the whole system. It seems to work ... except that I can not get the audio (alsa working). The device from udev is detected, but from alsaconf is not...
   It seems to be missing the initial configuration asound.conf. Does anyone know how to create it?
   I've done several tests but I don't understand it anymore. I would like a tip on how to try to configure the device from the command line.
   I attach the output of some commands, and the screenshot of my SliTaz-Build10 :-)

   Salve, a tutti.
   A proposito di LinuxFromScratch, i miei auguri per l'impresa di Filou e Shann, e nell'attesa di una distro ufficiale mi rivolgo agli esperti per un consiglio: mi sono costruito basandomi sulla guida LFS-BOOK-10.0 l'intero sistema. Sembra funzioni... salvo che non riesco ad avere l'audio (alsa funzionante). La periferica da udev viene rilevata, ma da alsaconf no...
   Sembra manchi la configurazione iniziale asound.conf. Qualcuno sa come si la crea?
   Ho fatto varie prove ma non ci capisco più nulla. Gradirei una dritta su come tentare da riga di comando a configurare la periferica.
   Vi allego l'output di alcuni comandi, e lo screenshot del mio SliTaz-Build10 :-)

   Adding sound instructions are in "BLFS:beyond linux from scratch" in the 'Multimedia" chapter.
   http://www.linuxfromscratch.org/blfs/view/stable/multimedia/libdriv.html
   The software may need to be patched before it is compiled:"LFS Patches Project"
   http://www.linuxfromscratch.org/patches/downloads/
   An asound.conf is configured by the user on an as needed basis.
   If alsa can't find the soundcard due to a driver issue an asound.conf is not the solution.
   https://www.alsa-project.org/wiki/Asoundrc
   Your lsmod output is showing required sound modules are not loaded!

   You should have soundcore.ko,snd.ko,snd-pcm.ko,snd-timer.ko loaded.
   Check /lib/modules/uname -r/modules.dep for loaded module depends that are not loaded.

   Thanks for the help mojo!
   The problem stemmed from eudev and its xxx.rules... which were causing horrible names to network devices. I had messed around too much, then I found a way around the problem (touch > /etc/udev/rules.d/80-net-name-slot.rules) and everything is working properly again.

   tux@slitaz:~$ aplay -l
   **** List of PLAYBACK Hardware Devices ****
   card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
   card 0: Intel [HDA Intel], device 1: ALC268 Digital [ALC268 Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

   despite everything the peripheral is set incorrectly and needs a fix in the drivers or you can work around it with a ~/asoundconf user that changes the default settings
   pcm.!default {
   type plug
   slave {
   pcm "hw:0,1"
   }
   }
   I still need to find out how to get audio with firefox (apulse?)
   -----------------------------------------------------------------------------------------------------------------------
   Grazie dell'aiuto mojo!
   Il problema mi nasceva da eudev e dai suoi xxx.rules... che causavano nomi orribili alle periferiche di rete. Avevo pasticciato troppo, poi ho trovato come aggirare il problema (touch > /etc/udev/rules.d/80-net-name-slot.rules) e tutto mi riprende a funzionare correttamente.
   tux@slitaz:~$ aplay -l

   card 0: Intel [HDA Intel], device 1: ALC268 Digital [ALC268 Digital]
   Subdevices: 1/1
   Subdevice #0: subdevice #0

   nonostante tutto la periferica viene settata in modo errato e serve una correzione nei driver oppure lo si può aggirare con un ~/asoundconf utente che varia le impostazioni di default
   pcm.!default {
   type plug
   slave {
   pcm "hw:0,1"
   }
   }

   Mi rimane ancora da scoprire come avere l'audio con firefox (apulse?)

   @gibor this sounds promising - how much Ram uses your idle desktop?

   htop is good tool to measure

   @Rerivero
   thanks for the tip! apulse was already compiled. the only thing missing was how to start it with firefox.

   @Kultex
   Allego lo screenshot di htop.
   Poi chiedo se qualcuno sa dove risiede, o come levare e reimpostare rlimit. Perché all'avvio mi tocca inserire nella riga del grub “ignore_rlimit_data” altrimenti mi da dei problemi nell'esecuzione di alcuni programmi tipo cc1 o firefox

   I have no idea about rlimits, but maybe this helps you - https://manpages.debian.org/jessie/manpages-dev/setrlimit.2.en.html

   114MB is really good - I have been cheating and I was working on a minimal fluxbox respin of MX-Linux - I am on 150MB - it will be ready the next days - so we can compare......

   Hi Gibor (and thanks for your wishes),

   as I see you already have a working full (?!) desktop.

   How much LFS vs SliTaz is your build?

   Do you have any experiences to share? Do's and don'ts? Or does (B)LFS provide all the necessary / interesting information?

   Cheers!

   Hi Filou, I try to answer you in order helping me with a translator....
   My build is still under construction, but I can already use it for ordinary things. For now there are working: firefox, thunderbird, the openoffice suite, mplayer, leafpad, mtpaint and three games installed without my knowledge during the compilation of some package (Block Attack, Checkers, Sudoku).

   The second question I think you want to know the size on disk, and if not try to explain better (sorry but the fault is mine, for what I understand of English).
   The build with all compilers installed currently occupies about 9.1Gb. The kernel sources are also included. All other sources are on an external partition and are about 15Gb.

   I would not know how to share a build as it is. Especially since it would be impossible for me to upload it.
   If you want advice on how to build it, I could try, but know that I'm not a programmer. My real training is in electronics and telecommunications. So I can make gross mistakes... I often go by trial and error, except to delve into the sources when they fail, to try to patch them to get them done.

   The intent is to get a linux build with the fluency and speed unique to slitaz. Now the boot is 10sec. At full desktop it's about 20sec total. Not bad compared to many others!

    Hi gibor,

    thank you for the information. I see that you work exactly like me, just that you continued on the LFS path as it seems and I took a sooner side-step into the slitaz direction.

    I'm impressed what you already set up, in fact Web, Mail and Office are the main uses for a PC, which you already achieved. It would be interesting to hear, which packages needed to most patching (and what type of patches) to get this far.

    sofia-m offered the do some translators work, as he said to speak Italian and English fluently and could help out.

    So if you have some knowledge to share, which packages made the most problems and how you solved them, this could be helpful. If you posted in Italian, I guess sofia-m could then translate afterwards...

    Thank you so far!

    gibor - can you make an iso of your system? - I cannot help developing, but maybe debugging something or configuring the desktop ???????

    Ciao Kultex, l'idea c'era ma la distro è troppo voluminosa. Per fare una iso da uppare dovrei riuscire a strippare una base ridotta per una live.
    Così per ora assomiglia molto ad una versione di Archilinux, con compilatori e s.o. che convivono nella stessa partizione, in modo da essere pronti per assemblare nuovi sorgenti.
    Siccome ci si innamora delle proprie creature, la trovo bella così com'è, senza packages manager ed altri orpelli che non nomino che giravano sottobanco...
    14Gb il filesystem con consumo di ram in idle di 90Mb ed un boot da 20” a desktop finito, che altro mi può servire ancora?!?! ;-)

    Tento nel provare a condividere una versione test ristretta del mio slitaz a 64bit. Il pacchetto da 153Mb contiene la root della partizione compreso il kernel 5.8.3. il tutto scompattato occupa circa 1Gb, e contiene le seguenti utilità:
    Gparted
    openbox
    lxpanel
    pcmanfm
    leafpad
    epdfview
    viewnior
    L'avvio richiede di passare al kernel l'opzione “ignore_rlimit_data” purtroppo debbo ancora trovare la causa di questa limitazione (sembra in mmap per la compabilità di gpg).
    Di base preparate una partizione in ext3/ext4 e scompattateci il file sopra (lzma).
    Passate al boot con un grub4dos già inserito o come credete meglio voi.
    Si può preparare anche per una live, ma intanto mi piacerebbe scoprire se si avvia su altri pc.

    I try to share a restricted version of my 64bit slitaz. The 153Mb package contains the root of the partition including the kernel 5.8.3. the whole unpacked occupies about 1Gb, and contains the following utilities:

    openbox
    lxpanel
    pcmanfm
    leafpad
    epdfview
    viewnior
    Booting requires to pass to the kernel the option "ignore_rlimit_data" unfortunately I still have to find the cause of this limitation (it seems in mmap for gpg compability).
    Basically prepare an ext3/ext4 partition and unpack the file on it (lzma).
    Go to boot with a grub4dos already inserted or as you think best.
    You can also prepare it for a live, but in the meantime I'd like to find out if it boots on other Pcs.
