Subject: PROBLEM: ES1371 driver & high-pitched buzzing
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

1) ES1371 driver in 2.4.2 produces high-pitched buzzing instead of sound.

2) AudioPCI/97 card in friend's Duron-based machine (very similar to mine,
but different soundcard) works fine under Mandrake 7.1 stock kernel
(2.2.15-4mdk), but produces only loud, high-pitched buzzing noises when
used under 2.4.2.  Driver is built into the kernel, appears to be detected
properly.  Problem easily reproduced from RealPlayer, XMMS and mpg123.

3) AudioPCI es1371 high-pitched buzzing

4) Linux version 2.4.2 (root@blueberry.wilee.chromatix.org.uk) (gcc version
2.95.3 19991030 (prerelease)) #2 Sun Mar 4 20:59:55 MST 2001

5) No OOPS.

6) Playing any sound using, eg. XMMS, mpg123 or RealPlayer.

7.6) No SCSI.

7.7) The player apps mentioned seem to advance their timers very slowly
when the problem occurs - this appears to be of the order of 2 or 4 times
slower than realtime.  I can't personally see in great detail - the machine
and it's user are on the wrong side of the Atlantic!
