Does anyone have an idea getting the sound of pinnacle usb2 working? the image quality is surpringly brilliant, but... my system: suse 10.0, v4l-kernel from cvs (updatet some two days ago...). soundcard:82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller, driver: snd-intel8x0. Input:PAL I tryed all the things:
-activating everything in kmix (also for the pctv usb2-device)
-switched the kde sound-system to alsa
-using different players: kdetv, Xawtv, tvtime
1. v4lctl -c /dev/video0 list gives me: "Mute: on" - is that the problem? I could not change this typing v4lctl -c /dev/video0 mute=off. 2. do I have to run some special things in background? 3. I couldn't update dvb-kernel from cvs - is this perhaps causing problem?
please read the Em2820 Wiki documentation, you have to use sox (or something similar) for piping the audio stream from the usb pctv device to your soundcard. -- MarkusRechberger
I've the same problem with SECAM (after some modification on the driver) with mute=on and I'm very sorry but Iwill hope a little bit more explanation to use sox if it's possible
help on starting
Hi!
I have a Pinnacle PCTV USB2 and I'd like to try it out on Linux.
I read the wiki about this device been supported and I need some help on installing it.
Where can I download the package?
After download the package, do I need just to compile it or it is a patch to be applied on my kernel source or v4l source?
Thanks for the help,
Renato
just get the v4l-kernel from cvs and compile it:
$ cvs -d :pserver:anonymous@cvs.linuxtv.org:/cvs/video4linux login $ cvs -d :pserver:anonymous@cvs.linuxtv.org:/cvs/video4linux co -P v4l-kernel $ cd v4l-kernel $ cd v4l $ make ... ... $ make install $ modprobe em28xx
you will also need the kernel headers for doing all that

ioctl VIDIOCGAUDIO: Invalid argument
Hi,
I have a msi vox usb 2.0 tv tuner, i downloaded v4l from cvs and the compiler worked fine. When i modprobe em28xx my usb tv card its recognized and seted up. But when i run xawtv, aatv, tvtime, or whatever ... i get ioctl VIDIOCGAUDIO: Invalid argument and i cant see anything. My running kernel is 2.6.14-1, debian sarge distro.
v4l-info show the same thing, ioctl VIDIOCGAUDIO: Invalid argument and in the other line i get: ioctl VIDIOCGFBUF: Invalid argument
If anybody know what else can i do, i would appreciate it ...
cheers, Nitam.
Hi Nitam,
The MSI Vox isn't completly supported at the moment, I'll try to fix it during the next few days (only problem is I don't have that device and because of that I have to wait for others to test it)
Well, i can help you with that if you want, let me know if you need my email/msn/icq or whatever and i'll test your fix/updates.
regards, Nitam.

Can't tune any channel
First I'd like to thank you for allowing us to use our USB capture device on Linux.
I've downloaded the latest CVS of video4linux following the instructions you gave me.
My device is a Pinnacle PCTV USB2.
I'm having problems when I try to use the tuner, I just can't find any channel.
If I try:
mplayer -tv device=/dev/video0:amode=0:input=0:norm=3:driver=v4l2:outfmt=yuy2:channels=16-16,24-24,51-51 tv://
I got only static from the three channels above (note that if I try the same channels on Windows they tune ok). Looking at the output from mplayer I see this:
Couldn't find frequency for channel 16 (16)
Selected channel: 16 - 16 (freq: 0.000)
So I figure out that it was because of the frequency. I tried a lot of params like freq=483250 (frequency from channel 16 reported by Pinnacle Windows app) but still didn't work.
Anyone have any ideia where is the problem?
By the way, I'm in Brazil... here we use PAL-M and I'm trying to tune from antenna, not cable.
PS: I have tried others apps like xawtv, kdetv, zapping, etc... and the same happens with them.
Thanks a lot!!
Renato
Hi Renato,
could you try:
mplayer -tv device=/dev/video0:amode=0:input=0:norm=PAL:driver=v4l2:outfmt=yuy2 tv://
norm=PAL or NTSC
use H or K/L for tuning the channels
Markus
Markus,
Thanks again for helping.
I tried the command you gave me (PAL and NTSC) but I couldn't tune any channel.
On my Windows app, I have an option to select if the source from tuner is from Cable or Antenna. To be allowed to tune the channels on Windows I have to select "Antenna". If I select Cable I have the same problem that I'm having on Linux. Do you think the problem could be this?
I have tried some parameters for the module tuner but still no lucky, I'm trying:
modprobe tuner pal=1 tv_antenna=1
Thanks again!
mplayer -tv device=/dev/video0:amode=0:input=0:norm=PAL:driver=v4l2:outfmt=yuy2 tv://
also try different input values,
please provide what dmesg and lsmod shows up after plugging in the device
you normally don't have to touch any tuner settings.
Markus
Markus,
This is the output from dmesg after pluging the card:

Hello,
I am from Italy.
I have a "Pinnacle PCTV USB2 PAL Rev: 1.2" and I have the same problem of Renato (just (27 NOV 2005 12:40) downloaded the source from cvs and compiled/installed the driver). I noticed that the only channels I can tune are: 11 12 66 68 69 88 (tvtime)
In the stationlist.xml of tvtime I found this:
position="11" band="VHF E2-E12" channel="E11" position="12" band="VHF E2-E12" channel="E12" position="66" band="VHF Russia" channel="R9" position="68" band="VHF Russia" channel="R11" position="69" band="VHF Russia" channel="R12" position="88" band="VHF Italy" channel="G"
It seems that I can't tune UHF band channels.
Hope this info can help.

PCTV USB2
Hey guys, I'm totally new to these Wiki things, and Linux itself. I have managed to install the driver and get my PCTV USB2 device working pretty nicely on a program called "tvtime". However, there is no audio. I was reading the main page and was confused as to if it works or not. I checked out the usb audio section, and did this bit:
$ amixer -c 1 Simple mixer control 'PCM',0
Capabilities: cvolume cswitch cswitch-joined Capture channels: Mono Limits: Capture 0 - 16 Mono: Capture 4 [25%] [on]
$ amixer -c 1 sset PCM 5 Simple mixer control 'PCM',0
Capabilities: cvolume cswitch cswitch-joined Capture channels: Mono Limits: Capture 0 - 16 Mono: Capture 5 [31%] [on]
Except, my card had different information, obviously. So I was wondering if there is a way to make the audio work via usb.
Any help would be much appreciated. (Im using Ubuntu and tv time by the way)
NO SOUND----
I'm using PClinuxOS and TVtime (the only one tv wiever working for me with SECAM mode Tuner=38 in place of 37).Tv picture is very fine but no sound. The mixer is correct:
- amixer -c 0
Simple mixer control 'Master',0
Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 31 [100%] [on] Front Right: Playback 31 [100%] [on]
.............and so
- amixer -c 1
Simple mixer control 'PCM',0
Capabilities: cvolume cswitch cswitch-joined Capture channels: Mono Limits: Capture 0 - 16 Mono: Capture 16 [100%] [on]
Is a mute problem in PCTV USB2 ?
Many thanks for help
can you provide some more information:
cat /proc/asound/cards
you also need to pipe the audio stream from the USB Audio device to your soundcard. sox is explained on the em2820 wiki site, but you can also try a cat /dev/dspx > /dev/dspy where you have to replace dspx with the usbaudio device and dspy is the soundcard dsp device
hope this helps,
Markus
no sound
many thanks to marcus for help, I 've make a misunderstood with /dev/dspx and now with sox and I've sound but it's very strange. configuration: kernel 2.6.15-rc1 with v4l2 my tuner SECAM is (reference after open PCTV on inboard tuner-chip : FQ1216ME H-3) sound on channel 126 and picture on channel 125 and so one for all channels....??? the sound is on the next channel after picture channel and on the channel on witch I obtain picture I've only noise like misaccording frequency.
Have you some ideas. Many thanks
did you try to fine tune the channel? what does cat /dev/dsp[of your pinnacledevice] show up when a channel without sound is tuned in?
Markus
Tune UHF channels
Hi!
It's me again :)
I think Lorenzo found my problem. I've completely forgot that here in Brazil all open-channels are UHF (at least in my city) so I think that's why I can't tune channels.
Is UHF supported? If not, are there some plans to implement it?
Thanks a lot and sorry for disturbing you.. but I'm just getting crazy to watch TV on my linux box.
Thanks again!
Renato
the driver supports a quite big range of channels, did you ever try mplayer with the default config and pressing h/k? (look at the em2820 wiki site how to use mplayer with v4l2)
Markus
Yes Markus, I have tried using mplayer with the default settings you gave me and pressing h/k.. I tried all the channels in both direction but none of them worked for me.
Lorenzo sad that the same happens with him when tring to tune UHF channels.
Any ideias??
Thanks!!

PCTV usb2: sound problem
I also use tvtime with my Pinnacle pctv usb2 card. I can see the images, but my sound doesn't work too. cat /proc/asound/cards provides:
0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4
Intel 82801DB-ICH4 with AD1981B at 0xc0000c00, irq 11
1 [Modem ]: ICH-MODEM - Intel 82801DB-ICH4 Modem
Why is my tv-card not listed? Shouldn't the tvcard be the dsp1? when I try in vlc to watch tv, I receiver the message(after I set the audio do /dev/dsp1):
v4l demuxer error: mmap unsupported
with "mplayer -tv device=/dev/video0:amode=0:input=0:norm=PAL:driver=v4l2:outfmt=yuy2 tv://" I can see the pictures too, but I receive the message:
Audio: no sound Starting playback...
I use FC4. In the soundcard-detection, the pinnacle tv card is listed, and when I select test device, then I can hear a test sound.
Does anybode can give me some advice? I tryed now hours to solve the problem. thanks for your help
Laurent
When I use in mplayer the option immediatemode=0:
mplayer -zoom -tv driver=v4l2:amode=0:norm=PAL:outfmt=yuy2:forceaudio:immediatemode=0 tv://
Then I don't receive anymore the message no sound, but I still can't hear the sound. I receive the message:

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
- Try -ao sdl or use the OSS emulation of ALSA.
- Experiment with different values for -autosync, 30 is a good start.
- Slow video output
- Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
- Don't try to play a big DVD/DivX on a slow CPU! Try -hardframedrop.
- Broken file
- Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
- Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
- Try -nocache.
Read DOCS/HTML/en/video.html for tuning/speedup tips.

Video offset
I finally got my MSI VOX USB2.0 working and I believe its set to NTSC but the video is offset like a portion of the top of cut off and moved to the bottom. I have tried tvtime and xawtv and MPlayer and all the same result.
