The last thing I ~]$ sudo jackd -d alsa -device jack51 -inchannels 2 -outchannels 6Ĭopyright 2001-2009 Paul Davis, Stephane Letz, Jack O'Quinn, Torben Hohn and others. It has no options for channels, only FRONT (left-right) and SURROUND (left-right) no other controls, no LFE, no CENTER, nothing. That's why I wanted to play all the sounds directly through alsa without pulseaudio. Yesterday on pulseaudio I got speaker-test -c6 -twav to give sound on all the speakers including LFE (subwoofer).īut that worked only with speaker-test, sound settings of gnome still gave me 4.0 profile where I could test only 4 channels. Now I have just alsa: speaker-test -D default -c6 -twav gives sound only on front-left, front-right, but it gives no error on hwparams Stream parameters are 48000Hz, S16_LE, 6 channelsĬhannels count (6) not available for playbacks: Invalid argumentĪs pulse audio has no 5.1 profile for my hardware I decided to remove it completely, so I did.
