New Linux OS aimed at computer audiophiles: Voyage MPD
fl replied to nyc_paramedic's topic in Music Servers
Nick, thanks for your efforts. I don't think my problem is much an issue of software versions. (I first want to get the Ayre QB-9 running for 96/24 and lower files, so no USB Audio 2.0.) Since you have a QB-9: What does its display show when you connect it to your Linux computer, but no sound is played? (I would expect "---" but in my case I see a permanent "96".) I now did look into mpd, since it doesn't seem to delegate to aplay. (Using an NFS mounted directory to get some sample music files.) But again I wasn't able to play any files. The mpd log-file contains error messages like ... Error opening ALSA device "hw:0,0" (snd_pcm_hw_params): Input/output error Is your mpd.conf file which you use with Alix/Voyage and the QB-9 available somewhere or could you send it to me? Best regards, Frank -

Sorry if I wasn't clear enough. Of course I had copied 2 sample files on the machine to test the 'aplay' commands I have posted. But I don't want to play any files on the Alix board. The input is a raw pcm data stream via the network (received by 'nc') which I want to pipe into 'aplay' to send it to the DAC. (The data stream comes from a room correction filter, I can report on this another time. First I really would like to get the QB-9 going at all.) Regards, Frank -

No, the files 01.wav and 01_24.wav are in the local directory, and they are correctly found (the output of aplay shows the correct file formats). Frank -

As said above, no mpd is used, just 'aplay' (no music collection on the Alix). Frank -

I have not used mpd at all. There are no music files on that machine, it gets the data via ethernet and should play them with 'aplay'. But I have tried to change the 'hw:1,0' in my 'aplay' examples to 'plughw:1,0'; that doesn't make a difference. Frank -

Hi, I want to test a new Ayre-QB9 which I want to use with an Alix board and voyage-linux. I have used this board successfully with a Trends Audio UD10.1. But with the QB9 I'm stuck before I can begin: When I plug it in, it shows for a short moment the expected dashes "---" in the display. Then the display switches to "96", although no sound is played. The QB9 has all switches in "up" position, so I first want to get it running for 96/24 and below. I attach a txt-file with the output of some commands: dmesg (relevant lines) cat /proc/asound/cards aplay -l aplay -D hw:1,0 01.wav # 44.1/16 aplay -D hw:1,0 01_24.wav # 44.1/24 cat /proc/asound/card1/stream0 cat /proc/asound/card1/pcm0p/sub0/* lsmod | grep snd lsusb -v This is on a current voyage-mpd on Alix. Playing via the UD10.1 on this machine is no problem. The problem is similar with an Ubuntu netbook; but the QB9 seems to work as expected with a Windows XP on a netbook: shows "---" when nothing played, and WinMediaPlayer plays sample 44.1/16 and 96/24 wav-files. Any hints would be much appreciated. Regards, Frank
