Look! The good example of TV installation

LCD TV and sound installation

Just found that picture on the Unplggd web site. Probably this is the best TV installation I seen ever! No any visible wires and stylish audio components. I’d like to know more about that installation. So, if you have some info, please, drop the comment.

UPDATE: The installation is used KEF KHT 3005 5.1 surround sound system (thanks to Paulo Hoppe for info!).

ALSA 1.0.19 is out

Recently new version of Advanced Linux Sound Architecture (ALSA) was released. There are more then 1000 new features, changes and bug fixes in the version 1.0.19. The most interesting are following:

  • Improving support of HDA sound for ASUS V1Sn, MCP67 HDMI, Intel DX58SO, NVidia MCP78 HDMI allowed to pass sound over HDMI (very important feature for Linux-based HTPC owners).
  • Improving identification of HDA devices Nvidia, Intel, HP, Gateway, Samsung etc.
  • Improving support of old kernels 2.2.x и 2.4.x.

I already spent a few days to configure my integrated nVidia sound card for playing sound over HDMI. But without luck. It seems that kernel 2.6.22-14 (stable version LinuxMCE 0710 is based on it) has some problems with recognizing HDMI part of the card. I can see just S/PDIF and analog. Will try to install LinuxMCE 0810 used new kernel (2.6.27-x) and upgrade ALSA up to 1.0.19 to get sound over HDMI.

TechnoTrend DVB card and Audiowerk2 driver

After upgrading my LinuxMCE 0710 Beta 4 to final version I faced with strange thing. Sound and LiveTV didn’t work. I spent a few house to investigate that problem. And finally found that I have two sound cards and no any DVB:
linuxmce@dcerouter:~$ cat /proc/asound/cards
0 [Audiowerk2 ]: aw2 - Audiowerk2
Audiowerk2 with SAA7146 irq 16
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe020000 irq 20

By some reason system recognized DVB card as sound.

I solved the problem with sound just defining NVidia as default card:
asoundconf set-default-card 1

But still didn’t have any luck with DVB. Thanks for folks from linux-dvb mailing list solution was found. The new Audiowerk2 driver recognized all saa7146-based cards as sound cards:
static struct pci_device_id snd_aw2_ids[] = {
0, 0, 0},

To avoid that I just added snd_aw2 into /etc/modprobe.d/blacklist. Now my LinuxMCE works like a charm!
