Macbookでのubuntu環境は知らないのですが。というか、まだubuntu stdudio はインストールしただけでちゃんと使ってない...

ここに答えがありそうです。
http://www.hydrogen-music.org/forum/index.php?action=show_thread&thread=321&fid=0&page=1

qjackctlの設定で"realtime"を有効にすればいいようです。"frames/period"は1024で問題なし。

realtime権限は一般ユーザに設定することは通常はできないので、お手軽にやるなら、

$ sudo qjackctl &
$ sudo hydrogen &

のようにrootで実行させて様子を見てみましょう。私はこれでhydrogenを動かして、デモ曲を演奏してみたのですが、再生はこれで安定しました。

一般ユーザにrealtime権限をあたえるためには、realtime-lsmモジュールが必要なようですが、ubuntuではバイナリとして提供されていないようです。一般ユーザでrealtime権限が必要な場合は、カーネルがビルド可能な環境を用意してrelatime-lsm,realtime-lsm-sourceとインストールしてモジュールをビルドする必要があるでしょう。

realtime-lsm-sourceをインストールすると、 /usr/src/realtime-lsm.tar.bz2 が入ります。
su でスーパユーザになって、これをこのディレクトリで解凍し、 /usr/src/modules/realtime-lsm/INSTALLを読んでみてください。

なお私はlowlatencyカーネルを使っています。

以上ご参考までに:)

> 質問なのですが、lowlatencyカーネルというのはどうやっていれればいいのでしょうか？

パッケージとして提供されています。
"lowlatency"をキーワードにしてsynapteicなどのパッケージで検索してみてください:-)

jackを使ってhydrogenなどを動かすだけであれば、とくに不要かもしれません。

ちょっとわからないのですが、

> sudo hydrogen &
> とはやってみたものの、GUIでないとさっぱりなもので...

hydrogenはGUIのリズムマシン（というと乱暴ですが）なのですが、おそらく

$sudo hydrogen &
Password:

と表示された状態ではなかったかと思います。

Password: のあとにはtatsfさんのパスワードを入れれば、root権限でhydrogenが起動します。
ご確認下さい。

realtimeカーネルモジュールのコンパイルについては、上記の事からレベル的にまだ尚早と判断させていただきました。なので、勝手ながら回答は一旦止めておきます。CUIベースの操作ができないとあまりにも辛いので。

GNOMEならgksudo、KDEならkdesuがsudoの代わりに使えます。

anoirさま、gmaxさま、ありがとうございます。

qjackctl>setup>parameters>realtimeにはチェック（バツ）がはいっているのですが...
jackdが起動するとき"jackd -R"となればいいんですよね？

最初からやりますと、

tatsuo@tatsuo-laptop:~$ gksudo

ログインシェルのオプションをつけて"qjackctl"と入力。

  Major opcode:  145

Failed to open device
Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed

こんなメッセージが出てきて（どういう意味なのでしょうか?)ともかくqjackctlが立ち上がります。

gmaxさま、お付き合いいただいてありがとうございます。
今後ともアドバイスよろしくおねがいします。

ちなみに uname -aをやってみると

Linux tatsuo-laptop 2.6.20-16-lowlatency #2 SMP PREEMPT Wed May 23 01:49:41 UTC 2007 i686 GNU/Linux

です。

gmaxさま、長々とお付き合いくださって本当にありがとうございます。

サウンドカードは内蔵のものを使っています。
/proc/asound/cardsは

                     HDA Intel at 0x90440000 irq 21

でした。
geditで

pcm.builtin {
    type hw
    card "Intel"
}

ctl.builtin {
    type hw
    card "Intel"
}

pcm.dsp0 {
    type plug
    slave.pcm "dmixer"

pcm.dsp {

というのを~/.asoundrcとして保存。再起動しました。（あってますでしょうか？）

状況は以前と変わらず。やっぱりjackdを起動した時点でプチプチいっています。

sudo qjackctl/sudo hydrogenとやって~/.xsession-errorsを見てみましたが、多分.asoundrcのことは書いてなかったとおもいます。

gmaxさま、ここまでお付き合いいただいてありがとうございました。
自分でもいろいろググってみたのですが、

http://lists.ardour.org/pipermail/ardour-users-ardour.org/2007-May/006356.html

に

"Please note that your soundcard probably requires 3 periods/buffer to work
properly."

とあったのでbuffer=3 periodsにしたら、一応途切れずに動きました。
レイテンシーは大きいですが、当面はこれで使ってみたいと思います。

ちなみにlspci -vですが、
