Hi all,
I searched around on the list, there are a ton of related posts but I can't seem to find something that helps me fix my problem.
I'm using KnoppMyth. I cannot get audio from the WinTV card output by mythfrontend. If I connect a cable from the tv card to the sound card, then I get straight audio from the tuner.
But I need to be able to get the audio setup properly. Can someone help out?
Sound works in general, I can play mp3 files with xmms, for example. And also, I can get sound from the tuner if I connect the cable into the sound card.
Here's my current configuration:
0000:00:0f.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
0000:00:0f.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
0000:00:12.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97]
0000:01:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 440 AGP 8x] (rev a2)
I have the following modules for sound:
# lsmod|grep snd
snd_pcm_oss 48168 0
snd_bt87x 11976 0
snd_mixer_oss 18176 1 snd_pcm_oss
snd_ens1371 20708 0
snd_rawmidi 21540 1 snd_ens1371
snd_seq_device 8328 1 snd_rawmidi
snd_pcm 81156 3 snd_pcm_oss,snd_bt87x,snd_ens1371
snd_timer 22404 1 snd_pcm
snd_page_alloc 9352 2 snd_bt87x,snd_pcm
snd_ac97_codec 64720 1 snd_ens1371
gameport 5632 1 snd_ens1371
snd 47332 9 snd_pcm_oss,snd_bt87x,snd_mixer_oss,snd_ens1371,snd_rawmidi,snd_seq_device,snd_pcm,snd_timer,snd_ac97_codec
soundcore 9184 1 snd
My modules config : alias char-major-116 snd alias char-major-14 soundcore
options snd major=116 cards_limit=4
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 /dev/dsp* snd-pcm-oss
alias snd-card-0 snd-ens1371 alias snd-card-1 snd-bt87x
alias snd-slot-0 snd-card-0 alias sound-slot-0 snd-slot-0 alias snd-slot-1 snd-card-1 alias sound-slot-1 snd-slot-1
I've tried using both /dev/dsp0 and /dev/dsp1 in mythbackend, with different results, neither of which have produced sound. If I use /dev/dsp1 (which I thought to be correct given I'm using snd_bt87x) I'll see this in mythbackend:
2005-03-31 22:10:47.876 NVR: Only read -1 bytes of 4096 bytes from '/dev/dsp1
read audio: Input/output error
If I use /dev/dsp0, then what I get is a lot of static on the sound, starting at a low volume and increasing volume. I'm also thinking that /dev/dsp0 is the same as the OUTPUT device, not the input, correct?
I've tried playing with the mixer settings, using kmix.
I've also tried running these settings with amixer: $ amixer set Master,0 100%,100% unmute $ amixer set PCM,0 100%,100% unmute $ amixer set Line,0 75%,75% mute captur $ amixer set Capture,0 100%,100% captur
Any help is greatly appreciated!
Thanks
Ricardo
