Each time I use the snd_t4dwave for recording I get the following error: pcm0:record:0: record interrupt timeout, channel dead pcm0: <Acer Labs M5451> port 0x1800-0x18ff mem 0xe0000000-0xe0000fff irq 11 at device 6.0 on pci0 pcm0: <Cirrus Logic CS4299 AC97 Codec> How-To-Repeat: dd if=/dev/audio of=foo pcm0:record:0: record interrupt timeout, channel dead 0+0 records in 0+0 records out 0 bytes transferred in 0.999230 secs (0 bytes/sec)
Responsible Changed From-To: freebsd-bugs->freebsd-multimedia Over to maintainer(s).
I have the same problem on FreeBSD 5.4-RELEASE-p1. # dmesg | grep pcm pcm0: <Acer Labs M5451> port 0x8400-0x84ff mem 0xf0011000-0xf0011fff irq 5 at device 8.0 on pci0 pcm0: <Analog Devices AD1886A AC97 Codec> pcm0:record:0: record interrupt timeout, channel dead -- Marian Cerny <jojo@matfyz.cz>
I don't have the hardware available, so I can't reproduce this problem any more. I am forwarding some old follow-ups on freebsd-multimedia, so that they are noted in GNATS.

I have no idea why t4dwave(4) still uses legacy capturing mode(Sound Blaster compatible mode). It seems that M5451 support code lacks codec initialization. So I guess its ADC part was not activated. Try attached patch and let me know the result. -- Regards, Pyun YongHyeon
I have the same error message but on playback. Device is SiS 7018. [zhangweiwu@lugdunnum ~]$ dmesg | tail ath0: <Atheros 5212> irq 11 at device 0.0 on cardbus0 ath0: AR5212 mac 5.9 RF5112 phy 4.3 uhub0: 3 ports with 3 removable, self powered uhub1: 3 ports with 3 removable, self powered Trying to mount root from ufs:/dev/ada0s2a [rw]... wlan0: Ethernet address: 00:40:96:ae:79:d3 drm0: <SiS 630> on vgapci0 info: [drm] AGP at 0xe0000000 64MB info: [drm] Initialized sis 1.3.0 20070626 pcm0: chn_write(): pcm0:play:dsp0.p1: play interrupt timeout, channel dead Note the last line of error message is only after playback for about 3 seconds. The first 3 seconds playback fine though, with any software (tried mpg321 and xine -A oss). Since the patch you offered no longer can apply, I did the minimum change on t4dwave.c and compiled a new kernel, tried, without luck (same error mssage). What I did is: @@ -725,7 +726,7 @@ intsrc = tr_rd(tr, TR_REG_MISCINT, 4); if (intsrc & TR_INT_ADDR) { chnum = 0; - while (chnum < 64) { + while (chnum < 32) { mask = 0x00000001; active = tr_rd(tr, (chnum < 32)? TR_REG_ADDRINTA : TR_REG_ADDRINTB, 4); bufhalf = tr_rd(tr, (chnum < 32)? TR Looking at the source code the problem triggered by "while (chnum < 64)" should have been fixed already, thus this bug should be closed, mine is probably a different one. Anything to try for me?
