Hello, I have an IBM T41 laptop with an Intel8x0 built-in sound card that generally works fine under alsa. I have been trying very hard to get it to play friendly with mythTV and my Plextor PX-TV402U-NA. The developer of the Plextor Linux driver wrote me this:
*QUOTE*------------------- >From your previous posts, it looks like card 0 is your built-in sound and card 1 is the ConvertX. So you should be capturing from hw:1 and playing back to hw:0. Make sure you use 48000 KHz with 2 channels. There's no mixer in the GO7007 driver and there's only one input, so you shouldn't have any trouble getting audio capture configured correctly. If you're using the settings above and it still doesn't work, it's probably an issue with getting Myth to talk to your playback sound card. Also, if you're testing outside MythTV, keep in mind that you won't be able to capture sound unless the video encoder is running. -Nathan *UNQUOTE*----------------- At present, I have run alsaconf and setup the card such that my /etc/modules.d/alsa effectively reads: ----------------------- ... 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. # Phil per http://forums.gentoo.org/viewtopic.php?t=162832 # --- BEGIN: Generated by ALSACONF, do not edit. --- # --- ALSACONF version 1.0.10 --- alias char-major-116 snd alias char-major-14 soundcore 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 alias snd-card-0 snd-intel8x0 alias sound-slot-0 snd-intel8x0 ... ----------------------- At the same time, my .asoundrc reads: ----------------------- # cat ~/.asoundrc pcm.intel8x0 { type hw card 0 } ctl.intel8x0 { type hw card 0 } ------------------------ I have verified that the capture device works under Windows. When running under MythTV, I can get some relevant audio (mono, 8000Hz) via $ aplay /dev/audio1. I've done some reading on the .asoundrc file, but don't see how I should set it up for the capture device nor how I can pipe from one device to another. I'm hoping for some help. I'm willing to try ideas all day PST in order to get this working. At this point, I'm guessing I should have at least: ----------------------- # sound card pcm.intel8x0 { type hw card 0 } ctl.intel8x0 { type hw card 0 } # capture device pcm.plextor { type hw card 1 } ctl.plextor { type hw card 1 } ------------------------ Thank you, Phil ------------------------------------------------------------------------- Take Surveys.
