| Post subject: | PVR150 Soundless |
Ok I have been trying to figure this out for 4 or five hours now. I slapped in an auto-install this afternoon and got it up and running pretty quick, except the channels were static/snow. Unfazed, I went to the 150 guide on the wiki and followed instructions to install the newest version of ivtv, which happens to be: http://www.ivtv.tv/releases/ivtv-0.3/ivtv-0.3.7.tgz The version the initial guide uses was 0.3.3f, which seems to be quite out of date now--the link in the guide itself is now broken. Anyway, I forged ahead, and followed the directions, making and installing and then editing /etc/modprobe.d/ivtv So after some investigation I notice that when I modprobe ivtv, it fails at the mixer_input=2 parameter. So I comment that out. Bang! Video is perfect and great, but no sound. Btw I am just trying to capture audio from the tuner... nothing special. The next thing I tried was to use the exact same ivtv version as the guide, so hopefully it would accept the mixer_input parameter, but no luck! I am somewhat mystified by this, and I keep looking for a typo thinking I am going insane. I'd start trying different numbers for the tuner= parameter, but knoppmyth seems to autodetect correctly and the video is fine, so I'm not sure if that would help. Any tips/suggestions, or just an explanation of what mixer_input does would be greatly appreciated. I'm going to restrain myself from installing other old versions of ivtv and get some sleep. |

well I know absolutely nothing about the pvr150's, but the wiki said that the line you commented out was for capturing sound from composite not the tuner. I know on pvr250's that the tuner is 4 may not mean anything here. also you may want to make sure wm8775 module is still loaded. you may not be able to use that option but still need the module. Of course this is all conjecture as I've never used a 150. |

With a clearer head this morning I quickly figured out that the audio is coming into audio input #1 instead of #0. The method I had used to test this last night was ineffectual. So how do I set the default audio input to 1 instead of 0? I looked in /etc/init.d/set_ivtv_params but I'm not sure if this is the right place. |

There's documentation for ivtv's modules/drivers and programs in the tarball you downloaded. I'd look through there since it's changing all the time, you may find what you want. It's also important to subscribe and follow the ivtv-dev list if you're using the unstable branch. You'd then know there's some tweaking required for sound using recent drivers on some of the 150s/500s. -brendan |

Fixed. Just added the command "ivtvctl -q 1" in mythtvsetup as a pre backend startup command. Just to clarify for future reference this is with ivtv 0.3.7, r5a16, pvr150 non-MCE NTSC. |

My PVR150 is working fine, but also no sound on the tuner. Tried ivtvctl -q 1, but this returns the following error: ioctl VIDIOC_S_AUDIO failed: Invalid argument My modprobe.conf : alias char-major-61 lirc_i2c alias eth0 3c59x alias snd-card-0 snd-cs46xx options snd-card-0 index=0 options snd-cs46xx index=0 remove snd-cs46xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-cs46xx alias usb-controller uhci-hcd ## ivtv (PVR-150) #alias char-major-81 videodev #alias char-major-81-0 ivtv #alias tveeprom tveeprom-ivtv #alias tuner tuner-ivtv #alias msp3400 msp3400-ivtv #options ivtv ivtv_debug=1 tuner=38 ## lirc_i2c install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install lirc_i2c |
