[Alsa-user] Stereo Downmix with cmipci
Hello, I'm trying to get the AC3 output coming from a digital Video Card converted to a plain old analog stereo signal. For this, I connected the SPDIF out of the video Card to the SPDIF in of the soundcard (cmipci, CMI8738MC6). For stereo/pcm signals, this works. I get the digital signal converted to an analog signal at the speaker output of my soundcard. But if the TV-Station sends AC3 signals, apperently this is not downmixed to stereo by the soundcard. Moreover, it sounds like a helicopter. How do I have to configure the soundcard to convert the AC3 to stereo? This: # amixer cset iface=MIXER,name='IEC958 Mix Analog'on amixer: Cannot find the given element from control default Seemed promising, but it's not accepted by the soundcard. I had all this working once, IIRC. And -IIRC- the above command did work. Any suggestions? Regards, Hendrik - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Alsa-user] recording from /dev/dsp
record -D copy -f cd -t wav outfile.wav ecasound -i:/dev/dsp -o outfile.wav I found a way around this. Sort of. Since the files do get cached by the web browser, even if they don't finish downloading. I extracted their URLs from about:cache for the disk cache. about:cache - Disk cache device - List Cache Entries File - save page as. grep -i .mp3 ./saved_as_file.html tempfile1 grep -o http://[^]*\ ./tempfile1 | sed 's/\//' tempfile2 grep -i studioauditions.com ./tempfile2 tempfile3 wget -c -i ./tempfile3 There's probably a simpler way, but this one kept me from having to go to every individual file to redownload them or save as from about:cache. Anyway it works. And for some reason the flash player varies the volume level for various samples, which doesn't seem to be noticeable when playing the downloaded .mp3's from mplayer. Anyway enough rambling I guess. Couldn't get arecord to work good enough for either of my soundcards(usb_audio atiixp). It did sort of work for atiixp, but the resultant wav wasn't anything close to what actually made it through the speakers the first time around. - James - This SF.net email is sponsored by: Microsoft Defy all challenges.
