 Posted: Thu Feb 24, 2011 1:32 am Post subject: Need hw address for USB TV tuner WinTV-HVR-950Q |
 |
|
I am trying to get sound working in tvtime for my WinTV-HVR-950Q. I need help figuring out the hardware address for the sound.
There is a script in http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-950Q that describes how to get sound from the driver over to tvtime. The line in question is:
| Code: |
sox -t alsa hw:1,0 -t alsa default &>/dev/null &
|
It does not work as shown and the reason is probably that hw:1,0 is incorrect for this installation. I would like to know how to determine the correct value.
lsusb -v for the device gives the following:
| Code: |

Featherfoot,
That hw:1,0 is alsaspeak for the second sound card found on your system. If you look in you will see a controlCn file for each card.
So if you have 0, 1 and 2 try hw:0,0 hw:1,0 hw:2,0 and so on.
Sanity warning. The card numbers depend on sound card initialisation order, which is not a constant. You need to make your sound kernel drivers modules and edit also.conf if you get random ordering each boot.

Thanks for the answer.
When I tried what you suggested, it showed that none olf the controlCn's were defined, nor were the hwCnDm's.
Another person had suggested that the device numbers were visible on one of the screens of alsamixer. I found it by selecting F2 and then cards. The same information is in /proc/asound/cards.
| Code: |
jc@bopper ~ $ cat /proc/asound/cards
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfe024000 irq 16
1 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfbffc000 irq 19
2 [HVR950Q ]: USB-Audio - HVR-950Q
Hauppauge HVR-950Q at usb-0000:00:12.2-2, high speed

That solved the tvtime problem. The next part is the inconsistent order devices get assigned that you and other people allude to.
The Alsa HOWTO document doesn't really discuss the problem of having multiple sound cards very well, but I tried to follow that. I ran the alsaconf command to set up /etc/modprobe.d/alsa.conf, but it only seemed to put a trivial setup in alsa.conf, not one which accounted for multiple sound cards, which really doesn't help much. I deduced that I need to build some option lines with indexes on them. Two of the three fields was pretty clear. The definition of what the second field is is vague, though. It looks like a driver name, but that really doesn't define the device. I poked around for device names, but the names have been interpreted to make them user friendly. Unfortunately, there are only examples, not rules.
In the end, I set up a file with driver names and I get many outraged messages when the system starts up, so I think I set up the option lines wrong.
tvtime and flash still work, but I'd appreciate your input on how to set up the option lines.

jc@bopper /etc/modprobe.d $ cat alsa.conf

This is clearly wrong, as I thought it was and /etc/init.d/alsasound restart is not happy.
| Code: |
bopper modprobe.d # /etc/init.d/alsasound restart

This whole area is a mess. There are references to hw numbers, but it is really hard to figure out how to determine what these are.
Then there is the definition of what goes in the option lines for alsa.conf to define the device and how you determine what it is.
I appreciate that the maintainers are doing a lot for nothing, but it would be nice if somebody who understands this stuff could make it a little easier for the rest of us. |

Featherfoot,
alsaconf seems to work for a single card,after that, you need to edit it manually.
Heres my working alsa.conf for two sound cards.
| Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
alias snd-card-0 snd-hda-intel
alias snd-card-1 snd-usb-audio
# alias snd-card-x <kernel-module for sound card x>
## OSS/Free portion
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
#alias sound-slot-x snd-card-x
##
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
## OSS/Free portion - card #x
#alias sound-service-x-0 snd-mixer-oss
#alias sound-service-x-3 snd-pcm-oss
#alias sound-service-x-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# Set this to the correct number of cards.
options snd cards_limit=2 |
I've embedded some commented template sections to show how to extend it.
You can have up to 16 sound cards with the standard kernel.

Thank you Neddy. I will study your file.
One key thing I had wrong: "option" is supposed to be "options". |

Your tuner will be hw:2,0 there as a result. |
