Sound issues on my Hardy 64bit
Only way I can get the sound to work, is to set everything to OSS.
Now, a few links with hints/guides to follow:
Alsa:
need to have soundcore loaded:
modinfo soundcore
Multiple soundcards:
explicitly assign the default device numbers of our sound card drivers by adding lines at the end of the /etc/modprode.d/alsa-base file like this (These are mine):
options snd_hda_intel index=0
options snd_cmipci index=1
options snd_atiixp index=2
options snd_usb_audio index=3
You can use:
cat /proc/asound/modules
Generic troubleshoot:
to check if the system recognnizes the soundcard:
aplay -l
lspci -v | less
sounds module installed?:
find /lib/modules/`uname -r` | grep snd
The 10,000 Page Guide to Sound Troubleshooting:
Among several tips, this:
Create a new user and login with that: if sound works, it's an issue of user configuration
Another (older) guide on sound problems:
This is a quite comprehensive guide, with a "failure/success" path to follow. Nice.
PulseAudio fixes:
It says libflashsupport should not be installed.
this is confusing, since it's the only way I could find to let Flash produce sounds.
PulseAudio installation (Italian):
Italian guide to PulseAudio installation.
Makes use of most of the previous hints, and summarizes them.
Too simple?
A noticeable difference with the "fixes" page:
Here it uses ladspa without even checking its installation. In "fixes":
Install the required LADSPA plugins and tools:
$ sudo apt-get install swh-plugins ladspa-sdk
Maybe
Also, there is no editing of the /etc/pulse/default.pa and no note on the necessity of changing the
slave.pcm "plughw"
line in ~/.asoundrc (or /etc/asound.conf)
Surround guide (italian):
To be tested yet
---------------------------
Edit:
this might be the real fix: remove pulsaudio....!
Or even better, in the same thread: post 51.
Or still, I can keep my "OSS" settings: not brilliant, but working...!

Installazione Ubuntu Hardy Heron 8.04 AMD64
Di seguito i vari step seguiti, in forma di nota/promemoria.
CAP 0: mettiamoci in condizione di tornare indietro, se qualcosa va storto....:
Backup Dapper
Disinstallare software inutili
Fare lista sw
dpkg --get-selections > installed-packages.txt
oppure da synaptic (vengono meno voci. Perche?)
Fare lista di storia di installazioni con synaptic (export to txt)
Fare screenshot del menu applicazioni (magari c’e’ un file con l’elenco delle icone: verificare e salvare da qualche parte, cosi’ c’e’ un elenco delle applicazioni installate)
--> copiato i vari file .desktop (in usr/share/applications e in ~/.local/share/applications)
Cancellare roba inutile, anche dal trash
Copiare fstab, menu.lst, part table di fdisk, xorg.conf
Copiare bookmarks, dati thunderbird, dati utenti
Partimage di boot (5min), home (30min) e sistema (30min)
Partimage di partition table (http://www.partimage.org/Partimage-manual_Backup-partition-table)
dd if=/dev/hda of=backup-hda.mbr count=1 bs=512 Now, we will save entries of the extended partitions:
sfdisk -d /dev/hda > backup-hda.sf To restore:
dd if=backup-hda.mbr of=/dev/hda sfdisk /dev/hda < style="">CAP 1: Installazione sistema
Una guida passo-passo
http://www.howtoforge.com/the-perfect-desktop-ubuntu-8.04-lts-hardy-heron
il mio schema di partizioni:
| Device | Mount point | File system | size |
| /dev/hda1 | /home | reiserfs | 30GB |
| /dev/hda2 | /media/music_fat32 | vfat | 30GB |
| /dev/hda3 | /media/shared_fat32 | vfat | 50GB |
| | | | |
| /dev/sda1 | /media/winXP | ntfs | 30GB |
| /dev/sda2 | /boot | ext3 | 100MB |
| /dev/sda3 | / | reiserfs | 50GB |
| /dev/sda5 | /media/myth | ext3 | 50GB |
| /dev/sda6 | /media/distro | ext3 | 8GB |
| /dev/sda7 | swap | swap | 1GB |
| /dev/sda8 | /media/video_fat32 | vfat | 100GB |
L'installazione dal liveCD AMD64 va liscissima.
Mi ha cambiato i nomi delle partizioni (chissa' perche') e ora vede il disco IDE hda come sdb. A parte questo tutto tranquillo.
Ho mantenuto la mia home, sperando di tenere tutti i dati e i settaggi.
In ~35min ho la Hardy installata e pronta all'uso, con dati e settaggi conservati!
Cap 2: Personalizzazioni
Step1 - Ritocchi al sistema base:
Nautilus: enable delete
Font: pref/appearance --> subpixel smoothing
pref/appearance/advanced --> 96dpi
Services: admin/services --> rimuovere gli inutili (--> bluetooth)
Startup: pref/sessions --> disabilitare roba inutile
Uninstall: togliere programmi inutili (--> nessun programma tolto)
Update: ricaricare e fare update del sistema
Reboot
Al termine dello step1 (~15min), ho 47.3GB free (49.2GB dichiarati da system monitor) → usati circa 2GB in /
Proseguiamo con le installazioni dei software necessari a rendere usabile (ai miei scopi) la essenzialissima Ubuntu.
Installo tutto da Synaptic, per poter avere un log di tutte le dipendenze installate di volta in volta, in modo da poterle eliminare insieme al programma in caso di malfunzionamento
Step2 - I fondamentali:
Fonts: msttcorefonts
Compilare: build-essential
Posta: Thunderbird
Sistema: partimage, checkinstall, language-support-it
Java: gcjwebplugin (non funziona!) oppure icedtea: jre e plugin (ok)
Flash: flashplugin-nonfree, libflashsupport
(http://www.ubuntu1501.com/2008/06/play-video-audio-while-playing-flash.html)
padevchooser → fotte tutto!!! pare che ne' alsa ne' pulseaudio funzionino: devo usare OSS in pref/sound
pulseaudio fallisce cosi': audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: Failed to connect stream: Invalid argument
idem alsa e CS46xx (scheda Hercules Game Theater XP)
Ntfs: ntfs-config per abilitare/disabilitare scrittura su ntfs
Multimedia: vlc, DVD95, gthumb (da usare al posto di fspot), doppio click su un .mp3 e installazione gstreamer ffmpeg e extra plugins
Compiz: pref/appearance/visual effect à per abilitare effetti (compizconfig-settings-manager)
Repo: aggiungere medibuntu
Codecs: w64codecs, libdvdcss2
Internet: aMule
update e reboot
2ore circa, 46.7GB free
Step2b: Partimage di installazione base (root, boot). Root ~2.8GB
Step3 - Utili:
Software complessi o con molte dipendenze, che potrebbero appesantire il sistema o renderlo instabile.
Li installo uno per volta.

TV-out su Radeon Mobility M7 (7500)
Nel passato, con Mepis (e XFree86) funzionava (male) con atitvout.
Qui con xorg non sembra funzionare.
Ho trovato queste istruzioni, pero'.
E anche queste.
Ci devo provare.
c'e' poi un tipo sul forum di pclinuxos che ha fatto cosi':
Ran XFdrake:
Selected "ATI Radeon (fglrx)"
Answered YES to "proprietary" driver prompt
Took defaults for the card options / startup:
Graphic card options ____________________
|*| 3D hardware acceleration
| | Enable Translucency (Composite extension)
Graphical interface at startup ____________________
|*| Automatically start the graphical interface (Xorg) upon booting
Selected generic monitor 800x600 @ 60 Hz 24bpp.
Ran startx
The desktop came up on the TV, monitor went black.
Opened up a Konsole session and everything locked up.
I then booted back into text mode and ran XFdrake again and unchecked the "3D hardware acceleration" and rebooted.
The display came up on the TV and everything seems to work ok (no lockups so far).
I also ran the "/usr/X11R6/bin/fireglcontrolpanel" and selected clone mode for the 2 displays. After restarting X, both the
TV & the monitor were active.
When I get time I'll experiment some more and try to load MythTV, but right now I'm pretty impressed with GBPVR.

Recently tested distro
Sidux Gaia
Debian Sid, KDE, very recent Kernel, nice tools for TV and nice scripts and customization scripts.
Menu is confused, too many applications.
Nice way to approach a "pure" debian.
Also 64bit.
Klikit alpha
Very nice look, needs at least 192MB RAM in the virtualbox and it's still slow.
Kubuntu Feisty based, KDE, one-clik install, kooldock, to be tested deeper, but it's very promising and user friendly.
Too much "Ubuntu", though.
Still I prefer PCLOS, which is very easy to use for the beginner but also powerful and complete.
I'll keep a close eye on it.
SAM
PCLinuxOS, XFCE with Beryl, nice, cool, light and complete.
Wolvix 1.1.0
Slackware, XFCE, very light but complete.
Very nice for a light vitual linux.
64Studio
Gnome, very, very good distro for music. It introduced me to Rosegarden and Jack.
Yet it's pretty simple (as a distribution, software is tough!). Much better than the other distros I've tried in this field (ubuntu studio, dynabolic. musix still to test) and its pure 64bit. A i686 version is available too.
Dreamlinux and Vectorlinux
Only opened in VMware (which is too slow on my pc) thanks to bagside and his appliances.
Not liked much. Nothing distinctive at my quick look.
LinuxMint Cassandra
Ubuntu Feisty, Gnome, very nice look (much much better than Ubuntu).
Ready to use and simple. Most of the missing things in Ubuntu are readily available here. Not only the proprietary/closed source stuff (maybe philosophically not acceptable, but often very useful) but also amarok, among others.
Should I reinstall an Ubuntu-like gnome distro I might really consider to install Mint instead of the "original" Ubuntu.
Even more appealing is the KDE version, which I'll test soon.
With PCLOS (and klikit), Mint is to me the "best" distro for beginners or ex-windows users.
My Preferred Distro
Still, so far, my top distro depending on the environment:
KDE: PCLinuxOS 2007
Gnome: LinuxMint Cassandra
XFCE: Wolvix and SAM
USB drive: DamnSmallLinux, Puppy 2.15, Slax Killbill (depending on available size)

USB speakers
I think it might be a missing feature in KDE, more than a pclos issue.
The USB speakers are recognized as a different sound card.
In Gnome there's a nice setting were you just declare which soundcard is your default.
On boot it tries that card, if not present it falls back to the other card.
This works nicely with the USB speakers, just declearing those as the default card.
There are some annoyances when switching the speakers on and off, but it generally works.
Same feature is in Rhythmbox, if I'm not mistaken.
No way to find this in KDE or Amarok, though.
I've found an interesting post for Kubuntu, but should work on pclos as well.
Re: switching between USB speakers and PCI sound card
open a shell and type
asoundconf list |
In my case, I have
CK8S
UART
Headset
Since I know that CK8S is my on-board sound card and the headset is - A HEADSET, then I can create switches for each:
First new text file, write:
#! /bin/sh -f
sudo asoundconf set-default-card (your main soundcard - no brackets)
so mine looks like this:
#! /bin/sh -f sudo asoundconf set-default-card CK8S |
Congrats, now you have two cool looking icons (Ubuntu Dapper) that do
nothing whatsoever! Just kidding, go ahead and right click on each of
them. Goto properties and then permissions. Under owner, check off the
Execute option. Then click the close button at the bottom.
OK, are you ready? Click on the one for your headset - boom, it will
ask you how you wish to run this. Choose "in the terminal" and then
enter the password - you just changed the default sound card without
needing to hack the .conf file manually.
From here on out, just click as you wish to toggle between the two. You
may not have to enter the password each time, it's a timed sort of
deal.
If using to toggle media in a browser, you will need to close the
browser with each new toggle. With on the desktop media files however,
you will need to close whatever program you were using for the same
affect.
In addition, this also seems to clean up sound issues that are assigned
in Skype. In short, once assigned the settings in Skype are not staying
set.
