Don't know what distro you're using, but your description sounds allot like mine. Here's the setup guide I followed: (I am using Slackware 9.1)
http://home.comcast.net/~homebrewracing/Mythtv.txt Take a look at "===Install IVTV Driver===" section for a couple of tips on troubleshooting the pvr 250. It doesn't have much (if anything) on the audio setup but the video parts might help. The instructions in this section are fairly generic. Audio took me forever to get working. Here's what I ended up doing: (assuming you're using alsa and it's installed) 1. Run alsaconf, it will find your sound hardware and set up /etc/modules.conf #alsaconf 2. At the end of alsaconf, it says it will run rcalsasound (?? not sure that's the exact thing it tried to run, but it's close) to configure the mixer setting, but that program is nowhere to be found on my machine. I had to do it manually: #alsamixer , make sure the master volume is not muted (MM at top of slider means left and right are muted). Esc to exit and your settings will be saved to memory but not permenent. #alsa store , saves mixer settings #alsa restore , reloads mixer settings 3. Now go into X #startx 4. open a console and run xmms (very commonly found music player in Linux). It should play properly. I found that if this worked, mythtv would have sound. 5. Here's a couple of commands that I found to be handy: lsmod - displays list of kernel modules that are loaded (like sound and video). Here's what mine looks like: Module Size Used by Not tainted msp3400 19692 1 (autoclean) saa7127 7804 0 (autoclean) (unused) saa7115 7644 0 (autoclean) (unused) tuner 10208 1 (autoclean) tveeprom 7456 0 (autoclean) (unused) ivtv 790368 2 (autoclean) i2c-algo-bit 7144 1 (autoclean) [ivtv] videodev 5792 9 (autoclean) [ivtv] appletalk 20196 1 (autoclean) ipx 16676 1 (autoclean) lirc_i2c 3804 1 i2c-core 12676 0 [msp3400 saa7127 saa7115 tuner tveeprom i2c-al go-bit lirc_i2c] lirc_dev 8628 1 [lirc_i2c] snd-pcm-oss 37032 0 snd-mixer-oss 12280 1 [snd-pcm-oss] snd-ens1371 10980 1 gameport 1436 0 [snd-ens1371] snd-pcm 55080 0 [snd-pcm-oss snd-ens1371] snd-timer 13444 0 [snd-pcm] snd-rawmidi 12324 0 [snd-ens1371] snd-seq-device 3696 0 [snd-rawmidi] snd-ac97-codec 49264 0 [snd-ens1371] snd 30980 0 [snd-pcm-oss snd-mixer-oss snd-ens1371 snd-pcm snd-timer snd-rawmidi snd-seq-device snd-ac97-codec] snd-page-alloc 4716 0 [snd-mixer-oss snd-pcm snd-timer snd-rawmidi s nd-seq-device snd] soundcore 3332 6 [snd] pcmcia_core 39296 0 ide-scsi 9168 0 epic100 11180 1 mii 2304 0 [epic100] crc32 2880 0 [epic100] agpgart 43780 0 (unused) (don't know why appletalk and ipx are loaded, I'll have to look into that!) lspci -v - displays pci hardware that has been found. The capture board should look something like: (except mine is a pvr 350) 00:09.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2 Enc oder (rev 01) Subsystem: Hauppauge computer works Inc.: Unknown device 4000 Flags: bus master, medium devsel, latency 64, IRQ 9 Memory at d8000000 (32-bit, prefetchable) [size=64M] Capabilities: [44] Power Management version 2 apachectl start - starts web server (if you're using mythweb) apachectl stop - stops web server httpd -l - (lower case L) - shows modules that are loaded in apache dmesg | less - shows progress of drivers loading (like video and audio and others, q to quit) locate xxx (xxx is whatever file name you're looking for) - shows location of file(s) updatedb - updates 'locate' listing (good to run this after you install something) That's aaaalllll it took for my setup. Good luck, Don PS - Here's what my /etc/modules.conf looks like: # use this setup for the ckennedy drivers alias char-major-81 videodev alias char-major-81-0 ivtv # added for lirc remote control #alias char-major-61 lirc_i2c #add above ivtv lirc_dev lirc_i2c ### setup with original driver - stock 0.1.9 version######### #alias char-major-81 videodev #alias char-major-81-0 ivtv #alias char-major-61 lirc_i2c #options tuner type=47 #options saa7127 enable_output=1 output_select=0 #options msp3400 once=1 simple=1 #add below ivtv msp3400 saa7115 saa7127 tuner #add above ivtv ivtv-fb #add above ivtv lirc_dev lirc_i2c ######################################## # --- BEGIN: Generated by ALSACONF, do not edit. --- # --- ALSACONF verion 1.0.6 --- 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-ens1371 alias sound-slot-0 snd-ens1371 # --- END: Generated by ALSACONF, do not edit. ---
