Hi all, I'm full of problems this week. Hopefully this'll have a successful ending as well! Any time I try to open a midi file, I get an error "can't open /dev/sequencer" it doesn't matter what desktop I'm in (sometimes I hate arts); and I can't figure this out. Anyone got an idea? Wes

Yes, I'm using devf, and devfsd.conf exists, although it's mandrake's default. No, /dev/sequencer doesn't exist; should've checked that first. How would I see that it's created and bound to my sound-card? Wes On Sat, 2002-08-24 at 21:48, Michael Frysinger wrote:

umm, well, if you use kernel sound drivers, make sure you have midi support enabled. if you're alsa or something, g'luck, cause i'm not touching alsa ;) -mike ----- Original Message ----- From: "Wesley Allen" <wallen@charter.net> To: <wlug@mail.wlug.org> Sent: Sunday, August 25, 2002 06:11 Subject: Re: [Wlug] /dev/sequencer problems

what modules are these? How do I load them? Just found the files are provided in a kernel package, so I must have modules installed, but not loaded! Wes On Sun, 2002-08-25 at 14:04, Charles R. Anderson wrote:

First, make sure you have the proper stuff in /etc/modules.conf: # ALSA native device support alias char-major-116 snd options snd snd_major=116 snd_cards_limit=1 alias snd-card-0 snd-intel8x0 # this depends on your sound card # ALSA OSS/Free emulation support alias char-major-14 soundcore alias sound-slot-0 snd-card-0 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 Then, the correct modules are usually loaded by /etc/init.d/alsasound. So: /sbin/service alsasound start At least that's what does it on my RH system. -- Charles R.

If you're alsa or something, g'luck, cause i'm not touching alsa ;)
Why is this? Is it personal (e.g. you have no time for it), or is there something I should know before I start touching ALSA? -- Keith

As to the last question: It certainly is a bit trickier to set up, but that is mainly because it isn't integrated into most distributions or mainline stable kernels. However, now that Linus has accepted it in kernel 2.5, we will hopefully see more support built-in to the distributions. Once you set it up, however, it has more advanced features. Your applications would need to be coded to the native ALSA API to take advantage of most features, but there are some other neat things you can do without specific application support, like intercept the output stream for visual effects and/or recording. Major apps like XMMS (via external plugin), xine and mplayer have ALSA support. My main impetus for using it is that the i810 AC'97 codec support in OSS/Free sucks. Both the Dell machines I've used come with this braindead sound hardware. The older Dell wouldn't do bitrates other than 44kHz/16-bit under OSS (or it tried to do them, with abyssmal results). ALSA fixed these issues for me. -- Charles R. Anderson <cra@wpi.edu> / http://angus.ind.wpi.edu/~cra/ PGP Key ID: 49BB5886 Fingerprint: EBA3 A106 7C93 FA07 8E15 3AC2 C367 A0F9 49BB 5886
when helping people solve their alsa problems, the answer almost always was 'use kernel drivers' as soon as they did, their problems went away -mike ----- Original Message ----- From: "Keith Wright" <kwright@gis.net> To: <wlug@mail.wlug.org> Sent: Sunday, August 25, 2002 16:54 Subject: Re: [Wlug] /dev/sequencer problems
