Post subject:	kworld global TV terminator audio problems
I recently purchased a kworld global TV terminator and I while I am able to record video w/ out problems, the audio track always comes back blank. The audio comes through fine for live-time viewing with the following: Code: mplayer tv://"insert channel" -tv driver=v4l2:device=/dev/video0:chanlist=us-cable:alsa:\ adevice=hw.0,0:amode=1:audiorate=32000:forceaudio:volume=100:immediatemode=0:norm=NTSC Any ideas anyone might have on how to resolve would be greatly appreciated. This is an R5D1 system. Thanks! Marc

marc i have the same card i can get the video but no sound at all, can you post the extra settings that you had done for the sound to show up on normal tv viewing

I don't get audio with mythtv's live TV playback -- it only works when I play live TV using mplayer. I connected the audio output of the kworld card to the line in of my audio card and followed the instructions in the mythtv wiki -- http://www.mythtv.org/wiki/index.php/KW ... Terminator

Things have changed, although not gotten better. I found an article that suggests that one can obtain the audio directly off the bus instead of using an audio loop-back via the sound card (http://www.linuxtv.org/v4lwiki/index.php/Saa7134-alsa). I've modified modprobe.conf so that it contains the following: Code: alias ra0 rt2400 alias rausb0 rt2570 alias char-major-81 videodev alias char-major-81-0 saa7134 options saa7134 card=65 tuner=54 video_nr=0 vbi_nr=0 radio_nr=0 install saa7134 /sbin/modprobe --ignore-install saa7134; /sbin/modprobe saa7134-alsa options saa7134-alsa index=1 When I attempt to record a show in mythtv I get the following error msg in dmesg: Code: BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: cbd289e3 pde = 00000000 Oops: 0000 [#1] PREEMPT SMP Modules linked in: snd_pcm_oss snd_mixer_oss sg nvidia shpchp pci_hotplug intel_agp agpgart 8250_pnp tsdev lirc_dev ipv6 usbhid ttusb_dec ttusbdecfe dvb_ttusb_budget cx22700 budget_av tda10021 budget_ci budget s5h1420 budget_core dvb_ttpci l64781 tda8083 stv0297 sp8870 ttpci_eeprom saa7146_vv saa7146 mt312 tda1004x ves1820 stv0299 ves1x93 evdev dvb_bt8xx nxt6000 mt352 dvb_pll sp887x dst_ca or51211 zl10353 lgdt330x dst bt878 cx24110 dvb_core bttv i2c_algo_bit btcx_risc tveeprom autofs4 af_packet snd_ymfpci gameport snd_ac97_codec snd_ac97_bus snd_opl3_lib snd_hwdep snd_mpu401_uart snd_rawmidi snd_seq_device i2c_piix4 saa7134_alsa snd_pcm snd_timer snd soundcore snd_page_alloc tuner saa7134 video_buf compat_ioctl32 v4l2_common v4l1_compat ir_kbd_i2c ir_common i2c_core videodev parport_pc parport 8250 serial_core pcmcia firmware_class yenta_socket rsrc_nonstatic pcmcia_core video thermal processor fan container button battery ac genrtc ohci1394 ieee1394 ehci_hcd ohci_hcd uhci_hcd usbcore aacraid a100u2w 3w_9xxx 3w_xxxx megaraid_sas tmscsim raid_class megaraid sata_uli sata_sil24 sata_qstor sata_nv sata_mv BusLogic CPU: 0 EIP: 0060:[<cbd289e3>] Tainted: P VLI EFLAGS: 00010206 (2.6.17-chw-8 #1) EIP is at 0xcbd289e3 eax: cbd289e0 ebx: c07cf400 ecx: 00000000 edx: 00000001 esi: d2e2a280 edi: d6716200 ebp: d038bf34 esp: d038bf14 ds: 007b es: 007b ss: 0068 Process mythbackend (pid: 4217, threadinfo=d038a000 task=d2206a90) Stack: d8bfb263 c07cf400 00000001 cbd28e00 d8f5d717 d2e2a280 d6716320 cbd28e00 d038bf50 d8f5dbd1 cbd28e00 cbd28e00 00000010 c8ebd300 c9195198 c916244c c0171244 c9195198 c8ebd300 c40e3120 c8ebd300 c40c7060 00000000 c8ebd300 Call Trace: <d8bfb263> snd_pcm_detach_substream+0x63/0x70 [snd_pcm] <d8f5d717> snd_pcm_oss_release_file+0x17/0x30 [snd_pcm_oss] <d8f5dbd1> snd_pcm_oss_release+0x31/0xd0 [snd_pcm_oss] <c0171244> __fput+0x164/0x1a0 <c016f927> filp_close+0x37/0x80 <c016f9ca> sys_close+0x5a/0x80 <c0103177> syscall_call+0x7/0xb Code: b8 cc 00 00 00 00 74 2a 6f 73 73 00 2f 6c 64 2d 6c 69 6e 75 78 2e 73 6f 2e 32 00 02 00 00 75 12 89 45 f8 8b 80 94 00 00 00 50 35 <c4> 01 00 00 00 00 00 00 00 80 a2 e2 d2 00 00 00 00 00 00 00 00 EIP: [<cbd289e3>] 0xcbd289e3 SS:ESP 0068:d038bf14 I get a similiar error anytime I attempt to run alsamixer or alsaconf on this card.

Thanks for pointing that out -- I had not noticed it. I used v4lctl to turn both mute and automute off, but that has not sovled the problem. I still am getting a NULL pointer deference error. Have you gotten your card to work? Marc

Post subject:
not yet, still working on it.... by the way, did u notive 2 pin outs on the card itself, it says jp7 and jp8, they look like audio out pins, i even tried connecting a line cable from them directly to my motherboard, still no luck with that.....
